Big problems with Undo / History Queue in 22.2.0

Anyone figure this out? Its happening to me all the time now. Random sequences im working on just stop letting me undo and redo changes im making. Its always random. 

I use versioning like Jeff Bellune.

I also right click on my sequence in the project panel and choose Duplicate on a regular basis.  This allows me to have old versions within the project.

There are some actions on the timeline that can't be undone.  Position of the CTI is one example.

What is not appearing in the history?

Have you checked the setting in Edit > Preferences > Auto save? Is it set properly?

Also, open the History panel under Window > History. This will show the active number of Undo's present in memory. If you right-click the top of the panel, you may choose Settings and then determine the number of Undo's. If this is set to a very low number, you will not record that many history steps.

Hope this helps.

I am not, but that doesn't help you.

A technique that I use is project versioning. When you get to a point in your edit where you're happy with what you just did, go to File>Save As and save the project with a number after the name. So instead of just saving "My Project", you'd save as "My Project 01". You may even want to include a tiny bit of text to remind yourself why you saved that version, such as "My Project 01 - ready for keying".

If things go "just crazy" after that, you can easily return to saved project state that will let you try again.
