"Love the mod, but I've found a bit of a bug with hoppers when you set block sizes to 1!

The hopper will still suck items from a container above even if it doesn't have room, it then spits out the item on the top floor.

Also, if there is no room in the chest below, the hopper still pushes the item in, but then the chest spits it out.

I can kind of see why, the mechanism that changes the stack sizes fires AFTER the item moves. But it would be great if this could be fixed in a later version!"

I also seem to be having this problem, but instead of on 1-stack items, I changed eggs to 64-stack items. I think the same problem is happening to me where the "mechanism" doesn't fire until after the item moves.

Below is from an admin of mine.

"I seem to be having problems with hoppers. I have a chicken farm that uses water to push eggs into a hopper->chest->hopper->chest. well once the chest at the end of the line gets full and the last hopper fills up, it starts spilling them out all over the room. It is dropping them into the chest in stacks of 16 and holding them in the hopper in stacks of 64. Not sure if there is something I am doing wrong or not."
