Tekkit pipes items disappearing when chest full

[monkey_tastic]

I like my sorting system quite neat and tidy, in the older version of tekkit i had a system where pipes would... well ill show...

The image basically shows, the items come in at the top and head right, they then get sorted by a diamond pipe just say cobble is getting sorted first, (infront of the diamond pipes there are chests) (if other items are present they carry along the top before they are sorted by a different set of diamond pipes.)

Before the update, the items would flow correctly, get sorted by the diamond pipe, and if the first chest was full (the chest at the top) the items would then go down and fill the next two chests, any overflow would go right down to the bottom where the iron pipe is and that pushes all the spare items to a overflow chest/condenser.

Since the new update, once a chest is full (the first chest) the items seem to keep trying to go into the chest but dissapear and not miss the first chest and try and fill the next two chests up. Is there any way of overcoming this? because it just seems like all my items are vanishing into thin air if a chest becomes full.

hopefully this makes sence like it does to me

Bump, as I would like an answer to this problem too.
