Beware,

If you happened to have any BMAP* with a path like this,
BMAP* mtl3 = "maps\\textures\\map_d0_mtl_3.dds";
Which worked before.

You will need to change it to:
BMAP* mtl3 = "maps\textures\map_d0_mtl_3.dds";

Or you will get a compile crash with no information what-so-ever on what happened or where.

Took me all day to find that crash in our code, where 3 lines of code were set up with paths like.
