got an error in control.lua: attempt to index local 'surface' (a nil value)
stack traceback control.lua 106 ; control.lua 99
That's ... unusual. Did you by chance do something that deleted a surface shortly after something died/blew up?
I don't know but we played with warptorio maybe this was the problem.
... Ah. That might be it - if there was a cleanup pending on a surface when you warped away from it, there might be an invalid surface.
