Describe the bug
After updating to TechReborn-1.16-3.4.4+build.86 machines (grinder and electric furnace) that would drag input from Vanilla Barrels and automatically output to barrels (with version TechReborn-1.16-3.4.3+build.72), no longer take input from barrels. They will still take input from hoppers on the same side, and auto output still works.

Steps to Reproduce
Build machine, configure input and output (top input, bottom output, both automatically), put items into top barrel, nothing happens.
Replace top barrel with vanilla hopper and then it works normally (but much slower)
