Hi. There are some bugs in this game that ive encountered.
First its the disappearance of the UI. When entering a flashpoint, after waiting for 1 hour, half the UI disapears and there is no way to get it back except for relogging. But what happens when u relogg? You get kicked from the group. THANKS SO MUCH!
Press CTRL-U. Press CTRL-U again. That will fix the problem.
