Game crashes when I try to host or join multiplayer.

[PeptoBismark]

I've hosted multiplayer with the mod many times before and it worked, and only recently an issue arrived where it would work fine until it got to the "Start/Abandon Game Screen" where it would zoom in, pause, then proceed to crash without giving a message.

Any help?

Just an FYI, it only crashes when I use the mod, I can host and join vanilla games just fine.
