Reply To: “Undo (Command/Control + Z) broken

I have found this post searching for advices for this problem.
I use 15.1.2 and noticed this yesterday, when suddenly one cmd-z deleted dozens of newly created pages, after I made some text edits. Poof, gone.
So, yeah, the bug is still around, and it is really scary. I could totally imagine not noticing a bunch of very small adjustments being reverted instead of just the last one.
One thing I read somewhere else hint it could be related to preferences, caches, even workspaces (that might be, because mine is a fresh install on a brand new iMac, and the only thing I imported for now was old workspaces).
I’ll go and try trashing caches and preferences, see how it goes, and let you know… Fingers crossed.
