[Error]: script_set_reg: failed to set param 'Zeny' to -37769.
[Debug]: Source (NPC): AntiBot (invisible/not on a map)

make sure you put Zeny check before deducting Zeny...
and probably check Zeny if overflow if the condition is true

just put atcommand "@kick "+ strcharinfo(0); if you want to kick players
