I redesigned my base, trying to get a big tree or xmas tree to spawn in the middle. Nothing has spawned in there yet, not even a small bush. I placed all my buildings along the outer edge and left a big open space in the middle. The open spacing is surrounded by walls with nothing inside, to protect my base from raids at least.
There is a ton of open space inside but can obstacles still spawn inside with walls all around? Or should i remove one wall... maybe i've been unlucky in spawns?
Thank you for any helpful info
