Summary:
I’m trying to build a 1-story house with 2 rooms and with a stoneslab roof. The roof shouldn’t be the problem as I’ve done this many times before the same way without problems.
As you can see on the picture below, I’ve made a similar building, but without a wall inside.
EDIT: Tried removing the template, placing it again, still same issue.
EDIT: Tried placing the template in a new game, still the same issue.
EDIT: Tried Instabuild, still the same issue.
- Build a house.
- Place a wall inside the house, using the wall tool.
- Error and nothing.
Expected Results:
They should build the house 
Actual Results:
I get the error on the picture and a C++ Lua runtime error.
