I'm some 45 days into my current game and the erosion is in it's full swing spawning bushes, grass and tiny car stopping pine trees all over the place but there is some weird sync issue.
I cleared my base from all erosion stuff and went away from my base (Pretty far away) came back a day or two later, as I expected much of the stuff has regrown but it behaved weird, disappeared as I got closer/further from it and when I right clicked and tried to remove some grass my character went to the other side of the screen from the thing I clicked on was being displayed and removed it there.
Many things spawned by erosion within a single session can be rendered quite a few tiles away from their actual logical coordinates. No idea why this is.
Issue can be resolved by quitting to menu and reloading the save, after that all grass and bushes that were wonky will be rendered at their actual coordinates.
I can try to capture it on video if my description of the issue isn't good enough.
