Yeah sorry about that. The problem is code from an old game mode that we didn't get cleaned in time. To avoid it when you are loading maps type /coop mapname It is already defaulted to coop edit for the future thanks to the great work by Hirato. Take care and I hope you're enjoying -mike
The honest truth would be is that I don't know how to remvoe this time constraint.
The next release will feature a 'banana relay' sort of gamemode as mode 0, which is what servers default to, despite me explicitly telling it to default to 1 in the code.
