Greetings,
As i'm trying to implement formations correctly for multiplayer & offer additional tweaks here, there is a bit of clashing between the single player formations.

Until it is implemented, this will be a completly optional download, which i'll release soon, it will contain extra formations for multiplayer & co-op but it will clash with your single player formations, as a result you shouldn't get this unless you want to play co-op/multiplayer with more formations.

The downloads for the tweaks will be added soon.
