When you demolish a decayed structure or placeable, you get the materials. That’s it really. If that happened, there wouldn’t be any decayed structures on servers.
I got this idea because when I start a new PVP character I always try to get to level 60 by scrounging and living off what I find, and try not to build a base until I get to 60. I often demolish decayed things to steal what’s inside and it’d be even better if I got the building mats. It would be a huge incentive for players to keep servers clear of decayed empty structures.
I don’t understand how this would reduce overbuilding. Specifically, I don’t understand what decayed builds have to do with overbuilding. Can you explain?
Any decayed structure is automatically demolished by the game after spending 24 hours in decayed state.
