Wall Project Materials Issue
Sheet metal wall projects materials change to create a useless indestructable project.
Placed one sheet metal wall project.
Built a wall. Destroyed the wall. Did not remove the project. Used it again. 3 times.
On the third time the wall was destroyed, the 'bolt' materials changed to 'cloth packs 0/40' on the project (picture and all).
Attempting to delete the project returns 'You must remove materials', even though all materials are 0.
