Why you don't have two project folders ? In one the Server runs in the other you can work.
EDIT: and to answer: I have several project folders for that.
1. this bug only appears when several ppl join and fight at the same time
2. for this week, I'm not at home, so I only have a laptop here that is too slow for really playing the game. I only get 5 to 10 fps, and the server thats running at the same time on this machine does also get problems. so i can't even think of starting another server or maybe several clients on here
3. I don't know if it is possible to run several -sv server apps on one machine, but i'll be testing that.
EDIT: it is possible through "-port" command
