-Fixed an issue in Multiplayer where if either the host or the client is using a gamepad and are playing with someone who is using the mouse/keyboard, the host hangs when switching to the ending cutscene.
-Fixed an issue with certain graphic cards where it would occasionally display large black pixels in the middle of the screen.
-Fixed a potential crash when players try to reconnect after disconnecting during a conversation.
-We've implemented a fix that will revert the A/D reversed issue for people that are still reporting this issue.
