First off, I don't know if this is more a suggestion or a bug, however it seems more like a bad/wrong code or something esque bug. Sorry in advance if this is the wrong forum.
Platform:
PC-Windows
Situation:
While playing FFXIV with gamepad, if the gamepad turns off (disconnected) by a "autosave energy" or due a technical problem and turn on, the game will no longer recognize the gamepad and you are unable to play with it untill full-reboot of the game.
This happens in both windowed and fullscreen mode.
So far this game and FFXI are the only games that this happen. It should be able to recognize it and be able to keep playing with no problem.
