I was running an m10 Gen and after crossing the plain, for no reason I couldn’t attack. I thought it was my mouse but when I went to my inventory I could click so it was on the games end. I was the tank and I could not aggro mobs after taunt. If I blocked and left clicked my arm would move for a split second like it started to attack, but my character would then resume blocking.
After using reverse stab or maybe just any ability it released this action and I could attack as long as I didn’t stop clicking. After the combo I could not attack again if I stopped clicking for a brief second. Again I used an ability that attacks and I could attack again.
Relogging did not solve the issue. I completely closed new world and I’m assuming the character reset timer hit by the time I logged back in because I spawned in a town and had to re-enter the dungeon. Bug was gone.
