- Description: Trying to automate any of the machines such as Docking Station, any of the chambers, etc. Inserting seems to work just fine, but when extracting I'm getting a NullPointerException as seen in this stacktrace:

I've tried multiple mods for inventory extraction from Extra Utilities 2 transfer nodes to vanilla hoppers (from stack trace above).
From looking through code, I am assuming that since stack.getCount() == 0 in InventoryHelper and stack is getting set to null, it's not dealt with very well when getting back into AbstractSonarInventory.setInventorySlotContents: this.slots.set(index, stack); Since this.slots is a NonNullList, the validation complains, thus not allowing extraction to occur.
The behavior can be seen in one of my videos: 3:02 in this: https://youtu.be/1lHmZKwT4gQ?t=182
Think I may have a fix, but want to test first. Any info on how to build it? I'm missing dependencies for other mod interactions such as mcmultipart, minetweaker, AE2, etc.
