This is similar to the bug you fixed in 1.35, but it seems like at low resolutions, remeshing multiple times will sometimes lead to … weirdness. Spikes and holes.
Obviously, there isn’t much point in remeshing several times in a row, but it’s happening even when I’m working on one part of a mesh, then resmesh the whole thing to tidy up the part I was working on.
Here’s a video:
/edit: I just noticed that I do have on Rebuild multires (at 2) and I’m remeshing at 407. It just seems weird that remeshing several times with the same settings would cause an issue like this.
