Readjust the spawning biomes for all structures. Detailed information can be found in the gallery. (Remove Terralith from required and make it optional.)

Fix issues with overlapping structure generation.

Set the spawn weight of wild leader trainers to 0, restricting them to gym structures only. (This is an experimental update. If a wild trainer with a specific ID already exists, you will not be able to battle any trainer with the same ID that spawns in structures. A common symptom of this issue is the battle menu failing to load.)

Prevent other entities from spawning in structures.
