Someone doesn't understand.

If I'm right, the undef.def comes before everything else, in case someone had a custom TILES014.ART or TILES015.ART that had .def code for it. Thus, you must have edited it incorrectly to have the undef.def after everything else.

If you're right, then the way undefs work is by disabling all highres stuff for that tile number, before and after. That doesn't seem like a good way to have it work, though, IMO.

The thing is, I had undef code for the Nuclear Winter insignia and the end of level screen, and they both worked on my end. The only other thing in there is #3830, and I didn't test that in-game.
