Good Evening or whenever you are reading this,
I placed and conveyor lift at the input of a storage container. I placed the second part above it. I let items "flow" into the conveyor lift. They arrived in the container.
Then I replaced the lift (upgrade/downgrade) and it started to go from the bottom to the top. Even though that makes no sense. The lift was visually moving from the bottom to the top but no item got transported up, nor any item got transported down.
I hope it was understandable.
