Issue description:Fluid not actually being stored on the disk, appears in the fluid grid, cannot pull out of the grid. Fluid is Liquid XP:Ender IO.

What happens:

Fluid is imported via importer into the system. It will import with or without a fluid disk in it. It does not go into the fluid disk, but says it's available in the system. It is not available, and has been deleted.

More poking it has shown that any interaction with inserting via the fluid grid also deletes the fluid inserted, even if that fluid is available on an external storage.

No fluid disk, and you can insert fluid via the grid, shows the fluid available, but it isn't there.

What you expected to happen:

The fluid to not be imported if there isn't a spot for it, or import it and store it properly on the fluid disk that is available.

Fluid disks can be put into the disk drive when disk drive is in item mode, but think this is a separate thing, don't think it's a cause.

Steps to reproduce:

1. With or without fluid disk, have one item disk available in a disk drive. Have a disk drive connected
2. import the liquid xp from a tank. It appears in the fluid grid.
3. cannot pull out, not actually there.

I had an external storage for water hooked up. When I can get back on later today, I will set up another system and try it out again without all the extra parts in the system and see what happens and will report.

Also try with only RS (no other mods = DISABLE all the other mod jars).

Are you sure you don't have any fluid storage blocks / external storages connected?

Can you reproduce it just with RS alone (no other mods)?

That's what I thought. Thank you for reporting and for following up!

I found the issue. After messing around with it in an empty pack, it ran fine. I loaded the problem pack up and repeated the system I had issues with. I don't believe it's actually RS that's doing anything wrong. I had a cooking for blockheads sink on an external storage for water, and what seems to be happening is RS is treating it as a multitank and storing the fluid in it, I'm guessing because the sink shows a path to an "empty spot". It's not an actual tank though the fluid is just getting voided, so any refresh to the RS system causes the storage bus to refresh, and it no longer sees that fluid available.
