As the title says, when placing tile ghosts, I get alot of messages like this one:
3151.218 Script @stdlib/stdlib/core.lua:46: PickerBeltTools:PickerBeltTools/scripts/belt-brush.lua:40: attempt to index field 'place_result' (a nil value)
It might not be limited to tile ghost placing, but that is most easily reproducible for me. Factorio 0.18.40, but happens with 0.18.3x as well.
