For god sake...Before 0.3.8 introduced custom skins, anything below 0 and above ~300 was/is invalid. Scripts (gamemodes/filterscripts) are made to check for invalid ID's and block them to avoid crashes. When you add custom skin its negative number, and GM/FS see it as invalid. So open script, add new skin ID's as valid and recompile.
