Gas Rocket Port Loader Failure

Gas rocket port loader has gone to idle despite having power, gas and the rocket tank still not full.

The Rocket is actually a simple storage device at this time without engine or nosecone but started with the gas tank (Large) to be able to fill it fully with hydrogen - Selected 11,000 and hydrogen and attached a rocket port loader to the left hand side complete with power and input from several gas reservoirs full of hydrogen.

The loader commenced working - and worked up until the gas ran out. At this point I saved for the night and came back the next day - only to find that when more gas came along it didn't load this - it was showing idle despite having power and having gas in the input pipe - AND indeed 999.7g of Hydrogen in the Loader itself. [Edit - the loader had loaded 365/11,000kg on my save and can provide a save file if needed]

I found a work around - simply build a second Gas port loader onto the left of the existing one and as soon as it was built, the first loader immediately started loading!!! - even though the second loader had no power or gas input. I then deconstructed the second one and the first and original loader continued loading the remaining hdyrogen.

I haven't saved and reloaded again yet to see if this happens again, but suspect that adding a second loader simply resets a flag or a test where the initial one has now started failing the test.
