I sent a patch of my map to a few of my friends, but they keep telling me that the map is corrupted and keeps freezing. I even sent an entire map to someone and it still wouldn't work. However, the map in question worked fine for me, as does a freshly patched map. Does anyone know what would cause this? The only thing I could think of is if the shared/mainmenu/etc maps that entity needs are corrupted. I just don't understand why it would work for me and freeze for other people.
Also, this doesn't have to do with system linkability. The maps don't work for anyone except for me, even if done in split screen alone.
