Route your belts freely underground.
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Cant load mod. Error while running setup for entity "underground-belt-beltlayer-connector" (loader -1x1): next_upgrade target (fast-underground-belt) must have same collision mask. Can you help?
Looks like you are running an older version of the mod. What other mods are you running besides SE?
Just a few lol https://www.dropbox.com/s/jid3yg15l8dw128/mod-list.json?dl=0
Same Problem with Beltlayer But the Problem is not coming from Additional Turret or CMO

I got the same error but not from SE but rather Combat Mechanics Overhaul (same mod author ironically)
