I have a station with a large amount of storage and production. If I assign a large cargo container as Large:[SteelPlate:P1] then move steel plates from it to a connector, it appears to pull the contents of the connector back twice. I went from having 15K steel plates to 40K in a couple seconds.

It is a really cool Mod, but unfortunatley this means I cannot run it on my server till it is fixed.
