CAN NOT TRANSFER TO ANYWHERE

My 93 lv. mercenary is stuck in Part 1. after join a group at endgame. In Part 1.'s camp i can only talk to npc, but CAN NOT open my storage, also COULDN't transfer to anywhere using waypoints.
How's this? Another character of mine (10 lv., also in 0.4) didn't encounter above bug. I'm frustrated cuz i want to keep leveling my mercenary, plz tell me the problem and how i can solve this!

damn, you're right. i remove the skill bind and problem solved. But it's still strange that i did not encounter issue before as i always bind this crossbow fire key on LMB. Seems like it's still a bug, just less harmful.(but tricky enough though)
