Ah yes, the inexplicable IWAD inclusions, heh. Guess I forgot to re-replace those when you submitted your update, this should fix it right up. As for the Zandronum error, I imagine it's to do with Zandro being based on an older version of GZDoom and therefore not able to cope with the newer stuff: ZDoom does the same thing when you try to load up the compilation in there.
