Fuel crossfeeds between stages even if crossfeed is turned off

[primal anvil]

I launched the ingame kerbal-k2 and when I was burning to the mun I ran out of fuel in both the stage I was currently on and the next stage which has not been staged yet. I looked into it and it looks like the first stage is draining fuel from both the first and second stage even though crossfeed is turned off on the decoupler between them.

Happens to me as well. I have tried to build 3 different rockets and it happened to every single one of them. Most of the time it was between the first and last stage, but sometimes it was with stages next to each other. I can't go anywhere because of this.

Yep I'm holding off until this is fixed. I have heard rumor that size adapters prevent crossfeed. If someone has success with this let me know.

Same problem too...

[sacred falcon]

Same issue very annoying

[rocky crow]

same for me

[graceful timber]

Yes I had same bug. I installed terrier on engine plate and after engine plate installed decoupler. I found bug when I decoupled stage and in my craft was little fuel, but in VAB tanks were full

Pic of the issue, might help

Ignore the "IN/OUT" in the transfer, they aren't doing anything

[wise niche]

Just adding that I'm getting this as well! Def needs fixed ASAP

[gritty gate]

Same here

[cerulean rose]

Yup same

Couldn't reach the Mun because of this bug. Please look into it.

same here

ok so apparently according to another thread, removing the XS or MD Landing legs fixes this...

[lament hull]

amazing, but it works.

[wispy silo]

Was having the same issue (see pic), but can confirm, changing from MD to SM legs seems to have fixed this for me too.

[hollow matrix]

Yep, fixed it for me as well when I tried again 🤣

Landing gear... causes fuel crossfeed??
All my wut

Just from a programming perspective, I have to wonder HOW those two are related. I'm not denying the evidence I just wanna know why lol

[fierce wolf]

For me It was the rover wheel

Btw i think all these kind of gameobject are based on the same struct and somehow the crossfuel Is enabled for that category of structs

[lyric solar]

I don't know, how the devs are playing KSP2 since a lot of months with theses bug...

[modern mirage]

This does seem to "fix" it, at least as a work around

[lime folio]

because these bugs were probably introduced in the latest build

for example, the pause/unpause spam was not in the preview build 2 days prior to the ESA event

[untold shoal]

Supposedly if you use medium landing legs crossfeed is on no matter what, I heard this rumor and it's affected me ever since so I could only imagine it's true as I've extensively reviewed the staging.

[lime folio]

I just did a Mun landing with the medium landing legs and they work fine now thankfully

[teal oasis]

pretty sure they fixed that bug in the latest update so it should work now

[lime folio]

yes that’s what I mean
