Some questions for interest:

  • are you (or/and your wife) using mods?
  • using a lot of build pieces from different build types (insulated wood and black ice and tavern, etc)
  • have lots of thralls/pets/followers?
  • have a tavern near the base(s)?
  • have a ton of stuff stored in lots of chests and craftstations?

I do envy your collective setup. My system is complete junk in comparison to yours. I noted I started getting more lag after the last Update, but I also combo-build, mixing build types, as well as having a ton of stuff stored. I do have a small base elsewhere on the map and don’t get lag there at all.
