Short description of error
Applying a mirror modifier with Bisect enabled on an object having an unapplied Multiresolution modifier before it corrupts the file and crashes blender as soon as any action is performed after the fact.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
- Open the attached .blend file
- Apply the already added Mirror modifier
- Try saving the file
- Click anywhere
Blender most of the time crashes instantly when applying the mirror modifier, but if it doesn't, trying to save the file after applying the modifier results in an error saying "invalid args". Clicking anywhere after applying the modifier crashes Blender instantly everytime.
What was expected to happen
The mesh blender generates after applying the modifier, before crashing on the following action, seems to be fine; so this behavior should be kept the same. Only the crash itself should be fixed.
