What it is, I planned to add 'see invisble' to the '#bot invis' option and forgot. 
"Do you want [invis undead], [invis live], or [invis see]?"
I'll try fix it today, mean time you can run this Sql;
	Code:
	DELETE FROM npc_spells_entries where (npc_spells_id >=701 and npc_spells_id <=712) AND spellid=80;
 And it should fix the problem.
Any spell that has become a #bot command, needs to be removed from the bots spell list.
