I followed your reccomendation, but it didn't solve the problem. I also tried decompressing the file using ucc, same result.
Using the .utx received in the zip file gives the same problem.
The error I receive is, "error following url" can't locate package, and depending on the map either fallout.wall or fallout.misc
Are these just poorly made maps?
And to repeat they are ctf-lostintime and actually dm-moo!
quickedit: For the record I get a similar problem with As-Shuttle and shuttle.utx. Both of these can be found on the redirect as well.
edit2:ctf-incinerator1b and ctf-incerator-le102 both fail with a fallout.base reference.
