I've been having an issue with hoppers and diamond chests. Normally when a hopper is feeding into a chest with another hopper below it,the items output into the chest first, then into the hopper underneath. But for some reason with the diamond chests, the hoppers feed down into the other hoppers first, and seemingly ignore the diamond chests if there is another hopper underneath it. It's destroyed my sorting system that I upgraded from normal chests. Is there some way to fix this?
Also, don't know if this makes a difference but I am using version 6.0.138 for 1.9.
