RL10A&B Dont Recognize Fuel Source

[KamikazeKricket]

Tried to use these engines, waited for them to deploy and they don’t have a fuel source. When you’re looking at the staging it’s as if there’s no fuel tank when it’s activated.

The same may be the case with the SLS Block I and Block IB upper stages as well, wasn’t able to check.

[blowfishpro]

Do you have CommunityResourcePack installed properly? Are the tanks actually filled with LqdHydrogen and Oxidizer? Just a couple of things to check first.

[DragonRoco]

Can confirm this a bug, but only on engines that have deployable nozzles (A-4, B-2), their status doesn't change from off. Clicking retract when the engine is fully extended results in the nozzle jumping back to the stored state, but clicking retract when the nozzle is in motion results in the animation playing in reverse, correctly (retracting the nozzle).

Log from VAB, deploying engines and then quitting to main menu.

Interesting -- thanks for the report. Will look into this one shortly, and should have it fixed for a release this weekend.

[shadowmage45]

Fixed, will be available with the next update.
