Sculpt stretches everytime I save file

So ive been having this problem where everytime I save my blend file after sculpting, it just stretches and glitches out randomly, and everytime I try to smoothen it out with the smooth brush and save again, the stretching gets worse!

Im sculpting with a multires modifier on this Godzilla model Im making. Thanks!

I just did a bit of research, and it seems this bug has plagued Blender’s multires system for a long time. In fact, multires has always been problematic and the bugs just keep coming back again and again over the years. The poor stability of this modifier seems to be one of the big things that has held back Blender’s sculpt mode over the years.

Thanks, didnt know that it was a huge bug
