Extending Corpse Timers

[Missneye]

Hello! I'm looking to increase the time until NPC corpses disappear. Right now every single corpse seems to be set to 12 minutes, which isn't ideal for nameds and such. I'm wondering if there is either a global timer I could change or a way to change individual timers.

I'm using the AXClassic repack with SoF, and there is no rule in my rule_values table that will change it. I also haven't been able to find a column in npc_types, spawn2, respawn_times, etc. Does anyone know how to change it?

These are the rules in my ruleset:

NPC:EmptyNPCCorpseDecayTimeMS
NPC:MajorNPCCorpseDecayTimeMS (Mobs > level 55)
NPC:MinorNPCCorpseDecayTimeMS (Mobs < level 55)
