Was pulled into combat and received the following error/popup that disabled my action bars (though I was able to mouse click the abilities). Error would keep occurring until I disabled to addon. Thanks.

1x [ADDON_ACTION_BLOCKED] AddOn 'Immersion_ExtraFade' tried to call the protected function 'MainMenuBar:SetPointBase()'.
[string "@Interface/AddOns/!BugGrabber/BugGrabber.lua"]:480: in function <Interface/AddOns/!BugGrabber/BugGrabber.lua:480>

also getting this error

Thanks for reporting. I was not able to reproduce this. I made some changes recently, which I don't know if they also resolved this issue. Please re-open this ticket, if it happens again. Ideally with a description of how to reproduce it.
