Had to pull the earlier update because Godot 3.5.2 handles pathfinding differently than the earlier versions, but it's now updated to use the new system and should work properly. There may still be smaller bugs related to the version change and I'll fix them if they come up.
Also a few fixes I forgot to mention in the earlier update:
- Brains are now visible
- Appendix has a unique model (It was already made, just forgot to use it)
