played 6 npc matches and finally got one to use an agent, and it didn't hang! so fingers crossed!
Small bug: I used Red Eagle cards to discard quite a lot of my deck and when I used the patron to pay 2 power and draw a card, it took the power but did not draw a card. This happened each time I tried in the same game but was okay in other games.
Controller/Gamepad will not work with Tales of Tribute
This player that posted in the link below was experiencing the same issue I was having.

I do not see any fixes for this in today's pts patch notes. I do hope the Devs see this as it is a game breaking bug for those that use gamepad. Not going to ping anyone as this entire thread, is already in Dev tracker so I am trusting that it will be seen. Please let me know - ping or PM me if you have any questions in relation to this that can help trouble shoot.
There's a condition that may be difficult to replicate, but in one match clicking on "End Turn" consumed my power against NPC opponent's agent even though I didn't click on it. Happened two turns in a row until the agent was gone, did not repeat on the next agent the npc played. Possibly because it was a taunt agent?
