Fonts changing in files when opened in Illustrator 29.5.1

I've experienced this twice now, both times in the last month. I design beer labels and I'll often open an older label and use it as the template for a new one. When I open the older file (an .AI file), it will load, and most of the live text will have switched to a different font arbitrarily. Some fonts switch to OTHER typefaces that exist in the same document, others switch to different weights of the same font, and still others switch to defaults like times and myriad.  Some of the switched fonts are stored locally, and others are served via Adobe Fonts. The file does this consistently even after I've restarted illustrator and restarted my computer. 

 

I've attached a screenshot of one of the files with its original fonts (from an outlined version for print), as well as a shot with the changed fonts.

 

Has anyone else experienced this?

Hello everyone,

Our team has attempted to resolve this issue in the latest Illustrator 30.x and 29.x releases. Kindly update to the latest version of Illustrator and try opening your files to see if the problem persists.

I understand that you are just following a directive from Adobe however as you are payed for your time Adobe's customers also need to make a living. Adobe MUST TAKE RESPONSIBILITY for insuring that this font substitution issue is fixed! It is not up to your customers to waste there time and money testing the your software, it is not 1985. Just go to your local Apple store buy 10 macs configure them in various ways and test them yourself. Then release the update notifying your paying customers that it has been fixed!!

The question remains. Hvae you confidently identified the issue that was causing it in the first place? And therefore been able to make the necessary code changes so it doesn't happen again. I appreciate that the illustartor code is probably an absolute behemoth nightmare of bodges, bolt ons and work arounds as it's never been rewritten from the ground up, but only 'developed'. But despite that I'm hoping your coders can give some level of confidence that a bug with such a core functionality has been identifies and sorted. Saying attempted is hardly confidence inspiring! If you do font critical work for print your latest version is still to be avoided until you can give us some assurance it's resolved.

So, to paraphrase what you said:  “ We called up the best of our Adobe tech coder cavalry and they ATTEMPTED to fix the random font substitution bug in Adobe Illustrator that has been going on for several months, costing Adobe customers thousands of dollars in lost time and possibly costing them clients".

 

To paraphrase a quote from Pulp Fiction, this is what we need to hear:  “You ain’t got no problem folks.  We are on the mofo.  Install Adobe Illustrator 30.0, chill out, and get back to work without any fear of the devastating random font substitution bug".

I just installed Illustrator 30.0 and tried opening a bunch of my older files, including the original culprit from the screenshots, and so far they are all rendering fonts correctly.

Good to know thanks. Still crickets from Adobe! You would think with all the money and support the industry has given them they would at least give us notification that they have addressed this. They want to take no responsibility and let us take a punt with a sample of 1 from a chat. Hope it continues to work for you.

strange that 29.0.1 also has this problem...
Should or should I not upgrade to 30.0?

That's pretty alarming as I was under the impresion that the highest version number without the bug was 29.4 which I'm currently using and have no plans to upgrade until Adobe can confidently say they've identified the source of the problem and solved it. I haven't noticed any fornt issues with version 29.4. to date.

 

Come on Adobe have you really sorted this? Can you confidently say you've idientifed the problem and sorted it.

I'm wondering where the abuse is here. My post was worded somewhat strongly due to the massive inconvenience this bug has caused and Adobe's essentially head-in-the-sand approach to it, but it's not abusive, as Adobe has been to my bank account over the last 20 years I've paid for this software.

There has been one report that 29.8.2 appears to have solved the font substitution bug. Can anyone else either confirm this as true or whether Adobe's struggle to produce commercially viable software continues?

I’ve downgraded to 29.4 for about 6 weeks now and I haven’t had the font problem so far.

Wait... did anyone else see this comment from 9/19/25?    It appears that the devastating bug that we have all been suffering from for months. at least for the one user below, has been fixed.  My response is yeah... right... sure.  If this were true, wouldn't Adobe be shouting from the rooftops that they have finally fixed the worst bug in the history of Adobe Illustrator?   I mean how much worse can a bug be  -  you do 3 days worth of work in Illustrator the same way that you have for 20 years, and you save the file, only to find that the next day your file is completely ruined due to some bug that f*cks up all f your fonts?

 

So, this solitary user says that this bug has been fixed by 29.9 or 30.0   It will take a hell of a lot more than that to get me to upgrade Illustrator past 29.4, a version that I know at least freaking works.

Ever since I lost a couple of days rebuilding files that were ruined by the font substitution bug, I'm very reluctant to use any version of Illustrator past 29.4. Is anybody still seeing the issue with the latest release, 29.8.1?

 

Thanks in advance for letting me know.

I am on 29.8 and it happened to me this morning. Sent final files to a client and had them come back to me to ask why one heading on one artboard was "not bold like the others". Illustrator had (yet again) swapped another font in the document in place of my heading font on a single word, on a single artboard, in a large project. Luckily the client caught it before it went to print but it still makes me look incompetent. And for that I am paying $100/m hmmmmm.......

Joining @Randy_111 in thanking you for the report. I will wait and deal with the lesser and more managable problems that arise from using an earlier version of this now cursed application.

Same issue here, shocking at the beginning.

I needed to print out business cards in a rush, but this happened when I opened the file.

I was able to fix it easily in 3 minutes after I read this thread. Thank you!

I installed Illustrator 28 and everything worked fine. I lost my preferences, but oh well—frustration is the feeling Adobe has gotten us used to.

Funny to think—now you can rotate your characters! But fonts fall apart and get messed up.
