Play it your way.
I got this error: Error while running event spawn-belt::on_marked_for_deconstruction (ID 20) spawn-belt/control.lua:40: bad argument #1 to 'ipairs' (table expected, got nil)

Should be fixed in 1.0.6, let me know if you still have issues. Opening a issue on the github page will get the fastest reaction.
