Operating system: MacOs Mojave and MacOs High Sierra
Graphics card: Radeon Pro Vega 56 8 GB and AMD FirePro
Broken: Version 2.83.2 (2.83.2 2020-07-09) and Version 2.82a (2.82a 2020-03-12)
Worked: in 2.80 zou can apply modifiers and this problem doesn't happen
"Rock" object will disappear if scaled, grabbed or rotated in edit mode or set origin in object mode. Same behavior was noted when the object was appended to a different project. Same behavior was noted through different Blender versions and tested in two different Mac computers. Imac Pro, and Mac Pro. I also noted that the error started occurring after applying the smooth modifier included on the attached file.
Exact steps for others to reproduce the error
Open attached file, select Rock object, go object set origin. Object also disappears if you go into edit mode, select all and tries to scale, rotate or grab.
The bug can be tracked by selecting Rock.001 that behaves normally until you apply the smooth modifier.
