Dock-able fuel tank fail. What went wrong?

[ajburges]

For my first Mun landing of a fresh career I took a different route: Typical lander that doubled as the engine for transfer stage tank (topped by re-entry pod). Cross-feed worked fine on the way to the Mun, but once I docked with the tank for the return journey (using RCS for the last dV to orbit) I found that I could neither draw fuel from the tank nor transfer its fuel to the lander for the burn. If I disabled "Resource Transfer Obeys Crossfeed rules" I could transfer the resources as expected.

Anyone know why a vessel that had fine fuel flow before decoupling did not allow cross-feed when re-docked to the original configuration?

Save file if it helps. Vessel(s) begin with "Luna 1"

This sounds nearly identical to a bug that the devs are trying to track down right now. In general we've found that doing a quicksave/restore after the redocking tends to make the fuel flow work correctly. Did you try that?

I though I did, but I could be mistaken.

I also forgot to mention that the save is modded. Vessel uses KER module.

• KER (prototype compile)
• Docking port alignment indicator
• Part Angle Display
• Precise Node
• RCS Build Aid
• KAC
• Waypoint Manager
