Broken:
2.8 hash ba1f178c1c8)
Worked: Unknown
**Short description of error**
When doing any sort of sculpting. Knicks, spikes, and discontinuities will develop 100 percent of the time when the 'subdivide' and 'apply base' buttons are pressed, even starting on a low-poly sphere at Multires level 6 with just a few random strokes. Both times, they will appear in the same locations, and apparently near the corners of the various patches produced by the modifier.
**Exact steps for others to reproduce the error**
Open the .blend file and press the 'apply base' button a bunch of times, the more times the worse it gets. Then reopen and notice the same knicks when the 'subdivide' button is pressed.

There's no fully sculpted head or creature here and it's just a few strokes on a low-poly sphere, anyone can create the same issue in about a minute. Hopefully these issues can be squashed for good as a result.
