[texture_rework] Load issues with BFG IWAD if 1.9 IWAD there

[mjr4077au]

Sorry for the gumby title, the length limits in the subject are really annoying.

As compiled with MSVC 19.5, if I place a v1.9 doom.wad IWAD into the directory, but load the BFG doom.wad IWAD that's found from Steam, it won't load properly and errors when going to E1M1. The BFG IWAD works fine without the v1.9 IWAD being there, and the v1.9 IWAD works at all times.

EDIT: This also occurs under the same circumstances for the doom2.wad IWADs.

How am I supposed to reproduce this? Using the BFG IWAD in my IWAD search path does not cause this type of glitch.

My situation here was the BFG IWAD was being found from Steam, but I had a 1.9 IWAD in my game directory. Having the 1.9 IWAD in my game directory caused the above to occur when trying to play the BFG IWAD.

The 1.9 IWAD played fine, and the BFG IWAD did as well when I removed the 1.9 IWAD from the game directory. Just having the BFG IWAD there won't cause the bug, it loads fine without the 1.9 IWAD.
