hello, ok heres my problem . currently im playing a fresh run with thorium mod plus remnants, and some QoL mods for easier building . the problem is I cant place walls in certain areas . For Example , the tree structure . idk why but the background of the roots of the tree are blocking it . This makes it hard for me to customise the base and also keeping the base free of mobs because they keep spawning in areas with no player-placed walls.
