5/5 Corruption bugged

[Codeine]

My 5/5 improved corruption cannot be cast while moving anymore, its just suddenly happened. it says you cannot cast this spell while moving, when 5/5 should make this spell instant cast. The tooltip says 2 sec cast time but if I cast corruption while not moving it casts instantly, while moving I get the error.

Anyone else get this? I've deleted WDB's etc and still happens.

its a bug when you quit your client with alt+f4, properly relogging fixes it

Relogging didn't fix it, relaunching client didnt fix it. And it occured after the server dc'd me.

Ok. I have specced in corruption 5/5 and it was working for me. I was runing around a npc and i tried to cast it while running and i had no problem with it. Corruption was working. Yeah and i got dc'd twice last night...corruption was working even after that...

The only issue I have is the "Can't cast while moving" with corruption. It's instant all the time. I'm wondering if the target is out of range by .5 yards or something and it triggers the gcd as if I applied the dot. Anyone else have this?

i had this bug on one or two other private vanilla servers..
as others said, mostly caused by bad client/server disconnection

another problem I had is the pet being unresponsive and pet bar missing

both of these problems were solved by hitting logout, wait 20 sec, exit gracefully.
deleting WDB and restarting wow sometimes a couple times
