I assume this is all you need, but if you want more i can always pastebin all of it.

 

ok ive done some testing and it happens when there is both an item conduit and a redstone conduit connected to the same block. When i put a filter into the item conduit, the redstone conduit causes some weird error. i remove the redstone conduit first, it works like a charm.
