Lo-Fi Games

The trees that grow around the lost lab at the end of the iron trail are growing inside the building. It's not possible to see through the foliage. You have to zoom very close to see under the tree branches.

The same is true of some of the building you can buy in the hub, it's annoying sure but I'm sure the development team are already working on fixing this, it's quite hard to miss lol

I've also seen trees inside the Hub buildings after they were purchased and repaired. I've also seen large boulders in ruined buildings which became invisible if the buildings were purchased and repaired but still blocked indoor movement.
