With 189 server been adjusted :
GlobalSpoilingTimeMultiplier=0
GlobalItemDecompositionTimeMultiplier=0
GlobalCorpseDecompositionTimeMultiplier=0
Spoiling time increased to 4x so 2mins should be 8mins etc.
Item decomposition (dropped on ground) 2x, so 90 sec is 3 mins.
Corpse decomposition 4x.
Test it, let me know if it works or no.
