Hi Crusard,
I don't have a lot of free time with my 2 young twins and my day work. But I plan to move coop or die to the KMQuake V2.19 engine. I think it will solve your problem and a lot of others (currently the mission 9 didn't work correctly).
I can't give you a date but in the worst case I will do that during the summer (end of july to begin of august).
For being honest I must tell you that I am more focused on my new game, I have sent you a short text description if you are interested to know (and maybe correct some of my english language mistakes
).
Here is a little scoop, the 1st screenshot of my new project available on the net :
