[Resolved] ship docked, cant transfer fuel

[Champ]

Hi all !

My favourite mods have now all been updated, so i can now test 1.2.1.

I've built a liitle lander. Brave ship has visited every biome on Minmus without refueling, then went in orbit around the mun and waited there until i built a refueling station.
Then, i built a station (fuel and lab), put it in orbit around the mun, and docked the lander to the station.

Problem : i apparently cant transfer fuel from the station to the lander. I have updated the R&D building to lvl 2 to enable ressource transfer, so the problem doesn't come from here.

Strange : i can transfer LS ressources, but not fuel

Edit : more info : Mods : KER, KAC, TAC LS, SCANSAT

Every decoupler or docking port has crossfeed enabled.

Is it possible that the problem comes from the heatshield just below the lander can ?

Can transfer fuel between the different tanks on the lander, and between the different tanks on the station, but not between the station and the lander

I have done some investigations : it was the heatshield. I have made the same lander without the heatshield, and this one can transfer fuel with the station.
Is there a way (a mod perhaps ?) to enable crossfeed through a heatshield ?

There's an option in the difficulty settings:  "Resource Transfer Respects Crossfeed Rules".  If this is enabled, you can't transfer resources between containers that are separated by a heatshield.  Apparently kerbals can figure out how to run electrical wiring and monoprop lines that route past heatshields just fine, but cannot figure it out for LFO.

IMHO it's stupidly limiting and I simply disable it, at all difficulty levels, as it doesn't add value in terms of realistic difficulty.

Thank you very much !
