ALL credit goes to DrX for his Desolation mod. All I did was increase the respawn time even further, from his 1-2 days, to 4 days.
Exact same as DrX's Desolation mod, all I did was increase those respawn times even further. They were set to 1 day for most things, 2 for some. I increased EVERYTHING to 4 days. Trust me, this isn't a fun thing to do. There are hundreds of manual edits that have to be made. It's incredibly painstaking and monotonous, so I did the work for you:) And no, this doesn't mean that every 4 days everything will automatically respawn like new again. The respawn timer doesn't start until a spawned in creature/NPC dies, so you will end up with varied respawn times almost immediately.
Addendum: This mod was formerly known as "Dan's Slower Spawns", but I decided to scrap that idea because DrX's Desolation mod is FAR better due to having more varied mob spawns. His work is amazing:)
I HIGHLY recommend using FullSimA-Life mod as well as DrX's Dynamic Factions mod together with this mod. With all 3 of these, I guarantee you will have the absolute most dynamic version of Stalker around:)
