"Partners in Crime" returns

Minor update - During this Valentine's Day weekend in Murder 4, the game master can enable the "Partners in Crime" game modifier!
10+ players are required and it replaces the Teams modifier for now. Some achievements are disabled, to prevent some bugs from happening.
I am working on fixing and optimizing a lot of Murder 4's code right now. Unfortunately it wasn't ready in time for this weekend, but it should be ready soon.
