Describe the problem

Since Patch 11.5 i have this Error Message in Bugsack

1x |cffFFA500cffFF5252ExtraAbilityContainer:SetPoint(): Couldn't find region named 'BossButtonHolder'
|cffffd200Stack:|r

Locals:

i cant find any solution to delete this error. The error also occurs when I have deactivated all addons except Bugsack and Buggrabber. Is it possible that this error is displayed incorrectly because other addons like the bug handler in SpartanUI do not display this error as a Lua error? The error appears every time I start the game or change zones.

BugSack collects errors in other addons, we're not looking for those errors to be posted here.

However if I was to take a guess, some addon has tampered with your edit mode profile. You can try deleting your profiles in edit mode and starting fresh.
