In various spots, a fallen tree object does not render, but you can collide with it. It sometimes fades in if the player gets their head very close. Foliage density setting seems to have no impact.
Very obvious as the tree/logs up to the floating house in Forest are now invisible. They can still be walked on, however.
Likely the same tree/log object used multiple times. Correcting the culling on it should fix them all.
