When I try run my mod in FitzQuake, and shoot a soldier, I get a blue head instead of a regular head... This does not happen in regular WinQuake and DarkPlaces when running my own mod.

(Sorry for the console being in the way... but you can see the head anyway)
I've pinpointed the problem to my progs.dat... but what is the problem?
I've tried using both the FitzQuake executable, as well as compiling my own FitzQuake. If I run FitzQuake without my mod on the target line, there's no blue heads.
Thanks in advance.
All my mod is, is a couple of editted .mdls, and some QC edits where you get pretty much more gore and what not.
