Windows Terrain texture issue

[Boogie]

Im new to this and dont know how this works. On standard farm layout, any season, theres a texture misplacement above my bat cave if you place something near it. I also remember seeing one near robins house. the tree on the left side of her house is also behind some cliff terrain. believe it happened on the green rain day

Hello, it's been 2 years but the overlapping texture still appears on the standard farm layout when placing buildings near the entrance of the cave.
I play in version 1.6.15 (build 24356) singleplayer on Mac (Tahoe 26.4.1), in French.
Lmk if any other information is required.
