One of them that I only found out yesterday is this one. It seems when you start the Maze, the previous scene is not unloaded. I did some changes to some codes that might have fixed it, if not please follow the instructions at the bottom of this page.
Second one is going to the Boss Room without any weapons, I also changed a few things, however I think it probably is not gonna fix it, if it happens. Please send me the log files.
Third if not being able to revive your teammate using medkits, send me the log files below just in case:
