The problem is: HOW PROPERLY SETUP WGL MOD ON LINUX DEDICATED SERVER?
I copied the wgl folder into server root, then ran the server with -mod=wgl option and this doesn't work. So i moved the files from wgl/bin folder to ofpserver root and it starts (even ofpwatch shows that wgl mod is loaded) but when i try to load any mission the server dies or comes back to selecting mission (i think it depens on the loaded mission requirements [wgl-die, noaddons-selection]).
