Nails on top of show

[RJIII]

This shows up near the cabins, also snow cover appears to flicker around this area.

Those are nails popping up through the snow (they are embedded into the wood walkway, which is just slightly under the terrain surface).

The flickering is "z-fighting" where we have two surfaces at almost the same location.

An art adjustment to raise the wood walkway would fix both issues.
