Can't build in certain places after update [HELP]

When Players or Admins Try to build Near Rocks or Caves I get This Error:
Cant Place: assets/prefabs/building core/foundation.triangle/foundation.triangle.prefab: Not in terrain

this error pops up when tying to build on any rock any location. I've tried on 5-6 maps all new generated
animals are walking in the sky like there walking up a mountain.

Trees are floating in the air just like nodes are. this is happening on every map we try.

Also. caves on the Map aren't in the location of it being showed on map. but the monuments are in the correct location.

please can someone help me, had to shut down the server until it's fixed.
-thanks
