Most of stuff that has miner style yellow arrows to indicate insertion side are broken and does not connect to reach other. This includes:
Assemblers, electric ore crushers(burner ones are fine)
Instead they drop their contents to the ground.
In a similar fassion 1x1 loaders are broken as well. They can not load to anything but they can empty from chests.
This is my first time asking for help in this platform, so I dont know which files are necessary to share, sorry in advance.
