Fonts changing in files when opened in Illustrator 29.5.1

[Lavish_coder1549]

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?

System:

2022 Mac Studio M1 Max

MacOS Sonoma 14.6.1

Illustrator v 29.5.1

I am having the same problem. I recently installed Adobe Illustrator en/ar version, because I needed access to the Arabic font direction text options. I don't exclusively work on Arabic documents, but had several projects come in, so had to switch over.

I've  only seen this issue on artwork files that were made in previous versions  of Illustrator, and the font switch is inconsistant - not every instance is replaced, but definately enough instances to make it very irritating. I work in an FDA regulatated enviroment, and fonts swapping without any notification is completely unacceptable.

Same. I just had this happen to me for a second time (the first time was about six months ago). They are food packaging designs, with several different fonts, and in both instances, Illustrator changed all of the fonts to different fonts. And not just the weights or to a default font, but to any other font in my library, it arbitrarily decided to grab. And like you, some of the fonts are local fonts that I own, and some are Adobe fonts. I use Extensis Connect as a font manager. I'm wondering if there is a bug (possibly in the plugin) with how Extensis Connect works with Adobe Illustrator.

I'm using Extensis Connect as well, and though it could be something about the plugin.. 

[sharah_0072]

My company is not using Extensis, so that makes me think it may have more to do with something in the Adobe software itself.

[John24472726qybf]

Does your company use a different third-party font manager software?

Just to clarify for those suggesting this might be related to Extensis Connect (or other plugins): that’s not the case.

As noted in several previous replies — including my own tests — the font substitution issue occurs even on clean installations of Illustrator with no plugins at all. The only consistent variable is the version number:
29.4 and earlier → no problem
29.5, 29.6, and even 29.7 in some cases → fonts randomly change on reopen

So this is definitely not an Extensis (or third-party plugin) issue. It’s a core Illustrator bug, and a very serious one.

I worked with Extensis when this first started to happen, and it is definitely not an Extensis Connect fonts issue. I installed the fonts locally and removed the Extensis Connect fonts completely, and the issue continued to occur. Since downgrading to version 29.4, I have not had any of the font substitution issues. Common Adobe, own up to this and fix it!

I'm using Connect as well – the problem only occurs after saving files in the new versions of Illustrator. I have got the original file (saved before this problem) and Illustrator always displays the fonts correctly. I can have the original (correct fonts) and the newly saved version (incorrect fonts) open at the same time, so my guess would be it's an Illustrator problem.

Noting for all that we've had the issue while using Apple's Font Book app. This is an Adobe problem, and now it's our problem as we are unable to use the software we are paying monthly for.

I can confirm the issue also occurs when using Right Font, font software.

Still happening in v 29.8.1

Just had this problem today with version 29.7.1 (2023 MBP M2 Max, Sonoma 14.6.1)

Fonts are all from the document itself but have "jumped" all over the place. So for simplicity's sake of describing the issue, the title was Garamond and the body was Helvetica. Now everything is Helvetica but if it was bold before, now it's regular, and vice-versa. Across the entire document. Quitting and re-opening doesn't fix it.
