[Vertex Group] "Delete all unlocked groups" not working
Open, IncompletePublic


System Information

Blender Version
Broken: 2.79b f4dc9f

Short description of error
I locked 2 groups, I clicked "Delete all unlocked groups" in the menu.
However, all groups are cleared, both locked and unlocked.

I found that its not working only after working a while on Blender, like assigning and removing vertices from groups, switch edit mode on/off etc.

If it's not working, the following steps can make it work again for a while, for unknown reasons...

  1. save
  2. new a startup file
  3. open the .blend file you saved in step 1

Seems I cannot reproduce this (I know you've mentioned it only happens after a while of working, but I did quite a bit of assigning/removing, obmode/editmode switching to no avail...)

The fact that this wont happen in a saved/reopened file apparently makes it even harder to reproduce.
Could you find the steps that actually lead to this behavior?
(Giving us the log of the Info-Editor [where operators and property changes are recorded] might also help...)

Marking as incomplete for the time being...

OK, trying.

Just found out that saved/reopened only fix it for a while, the "Delete all unlocked groups" will eventually be broken again at some point.
The real trigger is still unknown though.
