What the fuck does this mean?

This happens whenever I try to play my Community Chest 2 wad:

It's only begun doing that since I added textures from Doom 1 to the wad via WinTex. The textures are fine in WinTex and WadAuthor, so I really have no idea why they're making the actual game fuck up so badly.

[The Ultimate DooMer]

If you post it at the ZDoom forums, Randy (or someone else in the know) might have an idea of what's going on. In the meantime, try re-creating the wad file (copy paste the map only into a new wad) and re-doing the textures (in case it is something there that's causing it)

Looks like another -1 pointer bug. I've seen this kind of crash from zdoom posted on the forums several times now, so they're probably all related.

I thought of that too, but it gave me the same issue. To the ZDoom forums I go, it looks like :/
