Was working on the 2016 redux of the mod when I suddenly found out that the game unexpectedly crashes when warping to certain levels, ones I know off my head are MAP28, MAP29 and E3M6. It happens every time, so it's no just a random occurrence and 3DGE debug.txt tells me nada.

I've gone through all the DDFs, managed to eliminate COALHUDS, SECTORS.DDF, LINES.DDF and SWITCH.DDF being the problem. The problem seems to lie in THINGS.DDF but I can't for the life of me find anything anywhere that would be the cause of it. Tried to figure out what those levels shared in terms of things and checked if anything was wrong with said things, but no luck.
I've included the DDF files, no need for the WAD. You'll get a lot of yellow question marks and error messages but the game should still run (had to remove stuff from IMAGES.DDF, though).
