Zombies MOB crashing frequently.

[Sludge-Sock]

Recently me and a friend have been having issues with playing zombies on mob. Usually after about an hour of play the host will get a blackscreen, but sound will continue to play. After a minute or so the game will crash giving this error code.

Exception Code: 0xC0000005
Exception Address: 0x0074C175

This is nothing to do with AV as my game is whitelisted and most likely nothing to do with anything on our end as we've been playing Pluto zombies for years and we have never encounter this issue before. A fix maybe needed. FYI, we have only played MOB recently so we don't know if this is an issue on other maps.
