Game version 1.0.28
Normal game play.

When a tree is already on a build plot purchased, it's impossible to remove. Building over the tree still leaves the tree in place within the building. An identical tree from the landscaping build menu can be put over the top of it, and that can be removed, but the base tree on the plot still can't

Have tried all building types and landscaping tools, build, move and demolish and none of them seem to remove the tree. For me, the tree I'm having issues with is 3rd row down, 3rd column across from the top left.

Haven't tried buying other build plots with trees to test if it's just this one. I can see others have reported this previously and were told that building over it should remove it, but for me, it doesn't.

Edit: I've purchased other plots with trees to test. On all other plots, the trees and other foliage, furniture and ground tiles are removed, except the one I mentioned above. The large tree in tile 3 down, 3 across from the top left corner.

Tried starting a new game and purchasing the same plot - the tree still remains. See screenshot - https://steamhost.cn/steamcommunity_com/id/Emrystari/screenshot/5833924707409022551/
