Sorry for the slow replay, I did not see you edits till today.
The team map has set colors and teams. This is so that when you play as a team you will be next to you team mate and not scattered.
This is an option more for the 4 player teams than 2. It is an attempt to keep the game fair.
I can make a version for 2 players, with out these options if anyone is interested?
I was not aware that the map crashed. I have played it many times in multiplayer with no problems.
Doe's it crash at the start or as the game is played?
Are you in C2NW or BFE?
I assume that you found the problem with the menu since you have played the map with a friend?
