Fluids do not appear to travel through the mine cave pipes. So if I want to mine uranium from a uranium scrap cave, and I attach the pipe, the fluid gets drained from the external source at the expected flow rate but if I attach a pipe inside the cave itself a very tiny amount of the fluid actually shows up (25 after a minute or two, with each production cycle only leaking a very small fraction in). The rest seems to be voided.

Let me check

Thank you very much for finding and reporting this bug.

I have now fixed the fluid-transfer system for the Uranium Cave. Fluids should transfer correctly in both directions—from the surface down into the cave and from the cave back up to the surface—without most of the fluid being lost or voided.

The transfer system now tracks the amount the receiving pipe network actually accepts, so any unaccepted fluid remains at the source instead of disappearing.

Thanks again for the detailed report. It helped me identify and correct the problem.

Damn, that was fast. Nice work (and happy to help!)

thank you :)
