Reload game. That worked for me when I got that bug in Asgard.

I have just found that when I switched to Predator bow the ability worked. I've used light bow since beginning of game so a little heads up about that would have been good.

This doesn't seem to do anything. Suppose to be able to use this to destroy blocked doors instead of using oil jars but ability won't activate. The ranged poison strike works fine and uses an adrenaline bar and an arrow but when used powder trap nothing happens except a sound of an arrow firing. Only thing is you don't lose any arrows and you don't lose an adrenaline bar. Am I doing something wrong or is it bugged since patch.
