I'm using the drawers to stock my various ressources in project ozone, but when my system put more than 64 items in one drawer the excess disapears. I'm using extra utilities to take out and put items in drawer slaves. Any idea of qhat might cause this ? It is not doing it on an other similar system on an other map, and I cant reproduce the issue on a small system.

What version?

Same Problem.
Version: 1.7.10-1.10.9

When i put a drawer on a hopper and fill the hopper with cobblestone to block the itemtransfer and after that put a stack rotten flesh or anything else into the drawer, it will be delete until 64 items are remaining.

Note: When there's no hopper the items won't get dumped.

I'm having the same problem too. Playing Project Ozone 2, on a server, one controller with an extra utilities transfer node pulling items out (lootbags in filter). And now my Minicio Essence is being deleted.

Also new items to enter via the vacuum hopper beside it also don't appear.

After testing, they appear in the drawers for a moment and then disappear (new items. Old items have overflow over a stack deleted.)

I ran into the same issue while playing Project Ozone 2. From what I've observed this issue is caused by an Extra Utilities item transfer node (with a filter in it) pulling things out of the drawer controller. The only way that I know of to fix it is to use another type of item extraction method.

This exact thing has been happening to me for weeks and I only just realized it.

Version I have is 1.7.10-1.10.8

Other details as Ezkow mentioned are similar, I'm using ExU nodes to pull multiple items from controller slaves into autocrafters with rationing pipes to make complex Harvestcraft foods.

I will run some tests and see if I can be more specific.

EDIT: Other useful details, I'm using MULTIPLE drawer slaves with MULTIPLE filtered item nodes on each feeding into rationing pipes into easycrafting's autocrafters.

I've noticed something similar - or at least it's appearing to cap at 64. I'm not using void upgrades, but this is my test setup -

• 5x3 array of 4x4 basic drawers (except for the bottom-middle block which is the drawer contorller). (No Upgrades)
• For testing, I have 8 creative storage chests.
• I have a Thermal Expansion itemduct going from each chest to the drawer controller (with a servo for each chest)
• • Each drawer is locked and quantified.

I'm noticing that it seems to fill up the drawers starting from the top-left first, then the one just to the right of it, and when that is filled, the one to the right of that, and so on. So, other chests do not get filled up quickly. Within each drawer, it fills up one section of the drawer (1 of 4 slots) at a time. So, filling the drawers through a drawer controller is VERY slow. I've noticed this since 1.7.10. (I'm using 1.10.2)

However, if I put item ducts to each individual storage drawer, they fill up just fine.
