I tried version 0.2. It's not precaching model "sideweapons0.2.mdl"
Also, it has some warnings when compiling. Otherwise, in-game its working great.
PHP Code:
scripting\SideWeapons0.2.sma(99) : warning 203: symbol is never used: "g_flash"
scripting\SideWeapons0.2.sma(105) : warning 203: symbol is never used: "g_useless"
edit: Found that the file name was causing it not to precache. Removed a period sidewapons02.mdl and it worked.
