Worked: (newest version of Blender that worked as expected)

Short description of error
When saving with ctrl+S the last changes applied to sculpt with "grab" brush gets reverted. This should be observed by reopening the file.

Exact steps for others to reproduce the error

  1. Have a sculpt with dynamic topology. Disable dynamic topology for the next step.
  2. Move a part of the mesh with the grab brush.
  3. Save your last progress.
  4. Reopen the file using file browser. All changes done with the grab brush will be undone.

I cannot reproduce this on the latest alpha. Try downloading the 2.93 Alpha from https://builder.blender.org/download/ and see if that solves the problem.

I have downloaded the build of today 2nd of March and I still get changes reverted when saving using ctrl+S. Anyway ctrl+Z doesn't distort the mesh as much as before and using it twice and more also gets rid of the distortion. I have recorded a video that shows how it happens. I couldn't get the keystrokes to show up, but as soon as I press ctrl+S Blender freezes for a while. I am moving the mouse around as long as Blender is frozen. After ctrl+S is applied I hit ctrl+Z multiple times, at which Blender freezes again.
With the help of someone else I have found a workaround by exiting Sculpt mode after making changes and applying ctrl+S in object mode. That prevents this whole spiel, but adds extra steps to the workflow.

Thank you for your patience.

I just realized that I had a typo in the first description so I am verifying:

Ctrl+S reverts recent applied changes with grab brush
Ctrl+Z breaks the mesh afterwards.

This reminds me of the problem described in T76374, (which I was unable to replicate).

@Michael Giataganas (Deven) I removed the undo related statements since your last comment indicates that it is fine. If still an issue, please edit the top level box with steps to get the bug.
