[Crash] Infinite loading during loading map process in online cooperation


Green Slime
Environment: connect by IP, both story mode and arcade mode, frontline version
During my friend's and my game experience, the game sometimes get stuck permenently while loading the next map. the host and guest will see different loading animation, the host will see only himself successfully loaded the next map, so he is waiting for others, but the guests will see all of the members are prepared for the next map and those two loading process will not change again, so the game will be stuck. If guest shut down the game with ALT+F4, the host could continue the game with only himself. This happens nearly 1-2 times per hour, makeing it nearly impossible for us to finish the arcade mode because rejoining in arcade mode halfway is not permitted.
