In build custom building mode, I placed a roof on the building then removed it by using the green undo button. Then when I clicked the N W S E buttons to change the direction the roof was facing for when I replaced it and when I tried to put the roof back on it didn’t work and I got a couple of error messages.
The first error was: stonehearth/services/server/build/build_service/luac:318:attempt to call method ‘get_component’(a nil value)
Then lua runtime error.
Hope this helps you fix it 
I get this too, it really bothers me because I can never make up my mind on what roof I want to be 
But when this happens, the building design becomes useless, since it refuses to change roof direction and roof material.
Please fix
Hey guys, i’ve been experiencing this for the past few alphas, but when building my houses, my game gliches out and shows all these red error codes when i edit my roof in the build mode.
This can be solved by saving and restarting the game but it gets pretty annoying
