I'm cloning some of the mobs using 3000 ID and UP and add it to mob_avail.txt, everything works fine but I got the following warning message when starting my server.
[Warning]: script_set_constant2: Attempted to overwrite existing constant 'GHOSTRING' (old value=1120, new value=3188).
[Warning]: script_set_constant2: Attempted to overwrite existing constant 'INCUBUS' (old value=1374, new value=3189).
[Warning]: script_set_constant2: Attempted to overwrite existing constant 'SUCCUBUS' (old value=1370, new value=3190).
[Warning]: script_set_constant2: Attempted to overwrite existing constant 'MINI_DEMON' (old value=1292, new value=3191).
Is this okay? or how to ignore this?
