Set a blueprint with a piston without head in a projector and try to weld it.
You will receive:
ERROR while adding cube Piston: System.NullReferenceException
at Sandbox.Game.Entities.Blocks.MyPistonBase.ComputeTopQueryBox
I have try in Creative, Survival and Survival in Space Master.
I also try with a complex grid and in a void world with only a reactor, a projector and a blueprint of only 1 block (the piston without its head)
I have only try on big grid not small one.
