When i'm using refined storage to fill disc's with stuff, once a 64k disc is full, the items are stored somewere but not on a disk. Using Quantum disc's also show this issue.

Reproduce:
add at leased 2 discs in the drivebay
add items untill one drive is full, then add more items, disc 2 remains empty but items are stored in the system.

P.s trying to extract items with a empty disc using the manipulator drive does also not work, disc ejects right away.

Tried replicating this numerous times to no avail.

Will put it down as non-reproducible, but if it happens again after latest update, then please report it directly to the Mod Github.
