Recently I have found that if I use disguise to get into poisiton and unleash certain stealth attacks clicking the attack results in me removing my disguise and getting a message to say I need to be stealthed to use this ability...... no signs of stealth being broken prior to, its happening with npcs and with players and almost every 1st attempt (ie if I restealth it seems to work fine the next time through)
Anyone else having this problem?
