Enable/disable crossfeed button broken

[natoki]

Hello my savers,

After 2 years of IRL affliction (really a nasty disease to get IRLite), I'm finally back on a new gamer beast (PC master-race youhou !) and my 1st dedication is to KSP FULLY MODDED, like I used to love it so much.

 

But after 5 hours of gameplay, I ended being stuck with a tiny but very annoying problem, my [enable]/[disable] crossfeed button doesn't do a single thing anymore, on any kind of decouplers (vanillas or modpacked, radial mounted or inline) I can click the button as much as I want and it stays locked on enabled (or disabled dependently of it's last state)

Sometimes after a game reboot, it switches correctly one time on very small ships with only one or two stages of inline fuel tanks and then get stuck again...

 

Ok, EDIT:

after mod by mod selection test, I found the problem come when I activating mechjeb 2 by installing the autopilot module on a ship.

SO, Topic to move out, I'll go ask on mechjeb tech.forum.
