Echostruct

1. Fixed the issue of the shadow_altar structure floating again.
2. Fixed the problem of shadow_altar loot chests being empty. (If another bug pops up and deletes it, I give up.)
3. Removed the Listener achievement (this achievement didn’t make sense, and you couldn’t get it without having all the linked mods installed, really annoying).
The following content is related to the village link with Jerotes.
4. Added a new structure, Piglin Camp, naturally spawning in the Dry Volcano and Minglu Grasslands. You can use the Jerotes Village Piglin Outpost map to locate it.
5. Added a new structure, Disaster Encampment, naturally spawning in Minglu Grasslands. You can use the Explorer's Camp map to find it.
