I played last night for the first time this year, and had a odd issue. My Ninjas/Trick Arrow MM wasn't able to trigger his glue arrow. Entangle and Poison worked, along with my other abilities, but that one did not. It would get a circle around it if you clicked the button, but nothing ever happened. No Sound, no out of range, no pew.
So is it broken? Am I bugged for some reason?
