CommandZ Not Working

I’ve only been able to undo one or two times recently, before I could undo through multiple changes

Can you be more specific what you did?

Nothing in particular, was just modifying some handles, forgot to make a copy so I wanted to go back a few changes, but I could only go back a 2. I didn’t leave the glyph during the changes.

My file is using a ton of corners and segments, not sure if that can cause issues.

Edit; it’s back to working normally, just sometimes it doesn’t
