I am not sure if I should put this here or under the UI and addons category beacuse I'm fairly sure it's an addon causing this.
So as the title says every time I get interrupted while casting irregradless if it's by a stun, blind etc. my actionbars stop working. The next spell I cast has to be casted by opening the spellbook and clicking a spell in there which in turn makes the actionbars work again.
I am currently using the following addons: LazyPig, Ace 2, Align, Atlas, Atlasloot, Bartender2 (I've tried running default actionbars but the problem persits), BigWigs, Cartographer, ChatSuey, Chronometer, EquipCompare, EzDismount, Improved Error Frame, KLHThreatMeter, Luna Unit Frames, Mik's Scrolling...., Mobhealth 3, Mobinfo- 2, Natur ECB, oCB2, OmniCC, OneBag, PowerAuras, Sell Value, simpleMinimap, SuperInspect, Tiny Tip, XLoot, Bonho's Custom nameplates and Questie.
If anyone has an idea what might be causing this I'd be forever thankful.
edit: damn typo in the topic
