When using upgrade planner for example on a belt, the mod creates a non-recoverable error. This only happens in areas with robot construction coverage. (as far as I can reproduce it)
As a sidenote, I noticed that underground belts, when upgraded with the upgrade planner, only get replaced on one side with this mod.

Hope this helps you to maybe fix this bug! :)
