A few changes have been patched:

- Height display update corrected.
- Buildings and construction ghosts can be accessed from 16 meters away.
- Terraforming near building parts adjusted.
- Construction ghosts no longer block terraforming.
- Completed parts allow for nearby terraforming but prevent dirt touching the structure to be removed or lowered.
- Dismantling blocked when causing invalid situations (floating building parts).

Note: I'll see what I can think of for players to have more resources for building. One solution is to ask a Guide (a support ticket would work) to come to the test server and spawn materials that you need.
