Alright, whenever I try to host this WIP mod, whether on BEST-EVER with 1.0 or on my own computer with 98e-alpha-r3216 I get the above error and the server crashes. The map is UDMF, so it shouldn't be looking for a THINGS lump to begin with. Here's the file, could someone please figure out what inevitably boneheaded mistake I made? I haven't a clue.

HUB-MM8BDM-v0.8-hax-broken.pk3

Okay, your problem is that mmhub2.wad has a MAPINFO lump. Delete that (or move it to the top directory as mapinfo.txt) and you should be fine. It won't be read anyway if you have it inside a map WAD in some.pk3/maps/.
