Nimroy
When entering combat with another player (in a group), occasionally neither of us are given a combat menu wheel at the beginning of the fight and we have to alt-f4 to fix it. It seems to be focused on only one player, as long as that one player alt-f4 and can get their account to go link-dead, the battle can resume for everyone else in combat. The combat wheel appears for them.
We thought it might be caused by one player leaving the screen while another engages in combat. But it has happened even after we all confirmed before engaging. Any workaround to this would help, since it requires at least one player to always die to fix it.
