Okay so I just tried to test Annihilation today coop for the first time, and when i go to start the game it comes up and says patch_map_missing, I did compile the patch files as well as the other files, and all that but it still comes up that, i never had a problem with this on Fanatic, I did have to reinstall windows and i moved all the map files as well as the mod tools over to a separate hard drive and put it back on the computer once the install was complete, could that have affected it at all? I really would rather not reinstall the mod tools but if i must i will

patch_map_missing means the lobby tried to load a map which either the host or the client did not have installed completely or at all.
Check to make sure the mapname that the lobby is set to launch is correct, and make sure all participants have all the FFs and IWDs for the map.

That's why I used "lobby" in my reply. Have you done any modifications to your menu files? Are you using UGX Mod?

same thing happened to me, your map name is to long, I had to make a new map with a shorter name and copy everything over, but had to readd the scripts to my raw/mapname.gsc, there is probably a way to rename maps that I don't know
but thats exactly what i had to do so i gave you best answer, i had nazi_zombie_annihilation, and just had to remove the nazi_zombie_ from it then it worked coop.
