I do not know if this issue has been reported yet, but with the most recent patch, there seems to be a very serious bug with the summon spider skill. Currently, when my friend uses the summon spider skill, and the spider dies before the timer is up, the game gives him control of my main character as if it's one of his summons. Even after combat, I am completely unable to take back control of my character, and it seems that the only way to fix this issue is to quit the game and load back in. Has anyone else been having this problem?
