Not sure if bagon is at fault, but this popped up in my buggrabber, so I wanted to share.

Running Software (issues missing this information will be deleted):

• Addon version: 10.0.16
• Server patch: 10.0.5 (47936)

1x [ADDON_ACTION_BLOCKED] AddOn 'Bagnon' tried to call the protected function 'MultiBarBottomLeft:SetFrameStrata()'.
[string "@!BugGrabber/BugGrabber.lua"]:480: in function <!BugGrabber/BugGrabber.lua:480>

[string "TOGGLETALENTS"]:1: in function <[string "TOGGLETALENTS"]:1>

I'm still getting this type of error.

not only does it show this message, but it also locks the usage of action bar entirely at random moments! and you can never guess if your character will be just fine or would have to reload interface at every engagement. very fun at m+
