Route your belts freely underground.
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
An error happens when you try to decontruct an underground splitters, or whe you use a red blueprint and robots try to remove it
You should not be able to place underground splitters.
Well, maybe that's the problem lol
I actually can place them, at list the ones ultimate belts' mod gives you
I’ll check into that. It shouldn’t be possible, and the script is definitely not tested to handle splitters.
