Hmm, there shouldn't be two ship tables...
I'm not sure what the deal with decals is. Will have to check on that.
I removed aseffects because it was more trouble than it was worth, and was technically a mo, and the table was hacked up so that descriptions were tweaked, guns on ships and fighters were replaced, etc. One of the most common complaints was "Tables not working, fs2netd says they're hacked", and it was usually because of aseffects.
The one I went through and updated is the one in mv_effects, which will override the mv_textures one, so it should work properly. Actually, come to think of it, the one in mv_textures is probably set up to use the special Lilith/Leviathan texturees in case mv_effects is removed.
