Quote fromI've got a strange bug that isn't giving me an error message. I've got several bars stacked on top of eachother vertically, and sometimes an entire column disappears, but the key bindings for those buttons still function. Doing a /console reloadui or disabling, then re-enabling all those bars fixes the problem, but it happens fairly often.
This problem is because of the spellbook. Whenever I close my spellbook, it hides a column of buttons for no reason I can discern. The buttons are all functional but not viewable unless I reset my interface or disable/enable the individual bars again.
