The warning lies here: (line 71ish as it says)
PHP Code:
public Action:UpdateCounts(Handle:timer)
{ PrintToAdmins("Supply is loaded", "z");
// update fixed item spawn counts to handle 8 players
// These only update item spawns found in starting area/saferooms
UpdateEntCount("weapon_autoshotgun_spawn","17");
I'm sure you can see whats wrong there.
