Weird bug?

Well after taking a quest from Lions arch with my necro to ge to nightfall my necro lost al his casting moves,I mean when i cast spells with him he won't do the ussual spell casting moves he cast spells and clapping after this or just casting a spell with the staff...realy weird is this a bug or I did something that changed the behaviour of my character.

Thnaks in advance.

PS:None of my other characters that moved to Nightfall campaign has this problem.

I have had no problem with my necro it may be a problem with your data archive not sure though.

Mega Mouse
