Belts have been upgrading automatically and not being replaced properly, leading to unupgraded items clogging the belts they were replaced by. It has wrecked havoc on all of my space platforms, old furnace arrays, and generally ruined my factory run for any areas where belts were placed/upgraded since the mod update.
Please fix this issue - when upgrading a belt/loader/splitter/underground belt there either should be no removal of the old item OR it should fully remove the item and store it properly.
I am unsure why belts are even appearing on the neighboring belt network as this mod normally just upgrades the quality of the item placed without actualy removing the item and placing a new one...
