fractional bucket fluids just ... disappear (Gravitas 2)

[Gaelmare]

Issue type:

• 🐛 Bug

Short description:

When I use ID Tunnels to move liquids, they seem to just disappear if fractional buckets are generated and then moved.

Steps to reproduce the problem:

1. In Creative mode in the Gravitas2 modpack SSP (also observed in SMP)
2. Grab a GT creative cube, EV distillery, create creative tank, bucket of water, GT drum and ID cable, variable cards, fluid interface, and fluid importers from JEI
3. Assemble something similar to the pictured structure, with fluid importers set to "Import all Fluids" and the programmed circuit in the distillery set to "1"
4. Observe the Distillery create distilled water in 260mb increments

Expected behaviour:

Fluids to be transferred into the drum as they're created.

Actual behavior:

Distilled water is created then disappears. Removing the drum causes the distilled water to back up. Replacing the drum causes whole buckets of fluid to transfer, then the fractional buckets created afterward disappear again. Selecting "Check Fluid Amount" appears to help.

Thanks for reporting!

There's a single case in which IT would void fluids, and that's when the target container produces inconsistent simulate/real transfer responses. In that case, you will see a big error message showing up in your importer, and further transfer will be halted. Since this doesn't seem to be happening here, something else is going on.

I do however suspect either your source or target container may be causing the problem.
Could you try replacing your source and/or target container with containers with fluid containers from other mods, to simulate the same behaviour?
If the same can not be reproduced with other mods, then the mod owning that fluid container has an issue.
