Very, very odd thing.
When loading too many mods with own mod.cpp, the game freezes when trying to create en internet or LAN server. Nothing's logged in the RPT.

I first thought the problem would be within a specific mod folder, but after it didnt work even though I deleted the .pbos out of it, I deleted the mod.cpp aswell and it worked again. I then tried to leave that specific mod out but, indeed, as soon as too many mods with a mod.cpp are loaded, creating a server results in a freeze.
