While I have no issue with bulk export of single items (IE cobble gens and such), I have noticed that ouputting (in both export and auto modes) various items seems to freeze up direct export into chests. Basically it will only input into the first slot of the chest on the exterior and once that stack is moved the next item will flow in, and then freeze again.

This can be remedied by using a pipe of various kinds as an intermediary, but it would be nice if this worked by default as well. I have this issue in both my private modpack, the AT launcher modpack (modsauce?) and was confirmed in a thread on reddit.

Great mod, keep up the good work!

I will look into it when I get home from work. Sounds like a major bug, i hope i can fix it today and put out a new release.
Thanks for the report!
