[Snake]

If you disconnect during a fight, and someone with Total Control takes control of your character during your turn; If you reconnect during that, you can no longer control your character for the remainder of the combat session. This means complete loss of control. You cannot click the HUD, nor pressing any buttons will do anything, WASD mode or not.

There are currently no workarounds, even trying to reconnect during your ally's turn does nothing to amend this.

The only solution is wait until combat is over, and only then, relog into the game. Once you do that, you can control your char as normal.
