Summary: I was mining some clay and this specific "POI" seems to have some terrain bugs with floating, indestructable dirt blocks.
Game Version: (A21.1 b16)
CPU Model: (AMD Ryzen 7 3700x)
System Memory: (16 GB)
GPU Model and VRAM: (NVIDIA GeForce RTX 3060)
Screen Resolution: (1920x1080)
Video Settings: (Custom)
Game mode: (SP / RWG)
Did you wipe old saves? (No)
Did you start a new game? (Yes)
Did you validate your files? (No)
Are you using any mods? (No)
Detailed steps to reproduce the bug:
1) Go to the POI "Lazy Timbers" which appears to just be a field without Building.
2) Dig away The Ground at the same Place seen on the screenshot.
3) They are the upper layer, I can dig the blocks below (some of them are 1hit and make a grass sound which is weird too)
Actual result: Some Dirt Blocks appear that have a Hitbox, but can't be digged or destroyed
Expected result: Normally they shouldn't appear
