Blender Version

Short description of error

I'm getting this exact issue explained here: https://developer.blender.org/T52254

It's marked as resolved and after doing some digging, I can't seem to find anyone else having this problem. Therefore I've been unable to find a fix for it.

I'm using the latest build for 2.8, downloaded from the site. I have the amount of undo steps set to 50 and Global Undo is checked. Not sure if that information makes a difference.

Exact steps for others to reproduce the error

Open Blender. Start a new file or open a previously started one.
Turn on dyntopo.
Make multiple changes/marks on the sculpt.
Hit undo.
All previous progress will reset to the last save (?).
Do anything to the sculpt - touch it with a brush, rotate, hit Undo again, etc. - and progress will re-appear minus the last change. (Though sometimes it really appears to not have done anything.)

This started with d0fb602, but the real issue is that the sculpt PBVH does not exist after dyntopo undo.

Just some additional info though I don't know how helpful it'll be. The mesh only reverts to the point where the Dyntopo feature was lastly turned on from.

@akky111 it should already be fixed in the latest build.
