Modpack Version

10-4.6

Describe the issue

I'm using the ATM10 mod build and recently upgraded it from version 4.5 to version 4.6.

I recently discovered that some items in AE2 started disappearing, I tried to use the ME I/O port to track the bug and transfer items to new cells, but items from them just disappeared for some inexplicable reason, and I ended up losing 60%-80% of the loot (not all items on the disks disappeared, which also seemed strange).

As it turned out later, the ME system performs a kind of "rollback" in time, as a result of which some items disappear, and some old ones (those that were used before the rollback) reappear.

The rollback occurs about once every 2-3 minutes, but I have not yet figured out how often these rollbacks appear.

The server does not issue any errors or warnings and is not overloaded.

I hadn't noticed this behavior before upgrading to 4.6 (but my ME system was tiny at the time)

Having the same issue with different fluids from Modern Industrialization. In example Naphta and Sulfuric Naphta. I can start the Autocrafting for them and i even get the notification that the autocrafting is finished but when i look in my ME how much is stored it says 0.

I have encountered the same issue on modpack 10-4.5 through 10-4.10 on a server. Using an IO port to dump items from a cell into the storage arbitrarily deletes some items but not all. Isolating the network does not seem to fix the problem and there is plenty of space for the items to go to. We have resorted to not using IO ports due to loss of items.
