Rot Hide NPCs cast 'Curse of Thule' on themselves

the following SQL code will update any NPC that casts 'Curse of Thule' (all Rot Hides and Maggot Eye):

Quote

update mangos0.creature_ai_scripts
set action1_param2 = 1
where action1_param1 = 3237
and action1_param2 = 0;

also, based on a quick SQL search, the following NPCs will probably also self-cast these curses:

Quote

select creature_id, action1_type, action1_param1, action1_param2, action1_param3, event_flags, comment
from mangos0.creature_ai_scripts
where action1_type = 11
and action1_param2 = 0
and comment like '%cast curse of%';

Nice. Why not push the fix of the first spellcast, spell 3237?

As to other curses, one has to compare the spell structure. The 3227 spell has target type 6 (designated as TARGET_CHAIN_DAMAGE, but probably being the same TARGET_ENEMY as in 12340 client). So the spell must get an explicit target, i.e. would it be casted by a player, the player needs to select a target unit. Other spells mentioned above have target type combination 22/15 (TARGET_CASTER_COORDINATES/TARGET_ALL_ENEMY_IN_AREA), being essentially selfcasts with an AoE effect. The "self" target type is the one required by these spells.
