Not really. I reached like -80 altitude, then tried to transmit data and it exploded

I tried to land in Jool and... well... this happened

Oh my. I can't believe I made that mistake. Well after all everything was about the human factor :/

Here it is another image. About 2000 liquid fuel left while oxizider is almost finished https://www.dropbox.com/s/24f0843409wj3nh/Captura%20de%20pantalla%202015-12-19%2015.01.02.png?dl=0

Crossfeed in all decouplers is deactivated so that shouldn't be the issue if they are not bugged.

Sure, here it is https://www.dropbox.com/s/l5ekl07zf8ptyrb/Captura%20de%20pantalla%202015-12-19%2014.39.06.png?dl=0

Well, I don't have heavy mods I think, just the mechjeb one and the near future propulsion. I don't know if this may be the cause but I haven't touched anything else.

I usually set two Rockomax Jumbo-64 fuel tanks with the Mainsail engines. Without adding or removing anything normally I have aprox. 1000 fuel left when it runs out of oxidizer.

Sometimes, specially with the "Mainsail" engine, I run out of oxidizer when there is a lot of liquid fuel remaining, so it is a waste of resources and increases weight. I couldn't find an oxidizer-only tank. Is it planned in development or something?

Hmmm actually it seems legit. Thanks to both!

So it's all about the modules... I was thinking maybe in the pilots experience

I only have stabilize, prograde and retrograde modes and I can't figure out how to get the others.

No problem! Thanks anyways for your long-version answer!

I see! It was so simple but I couldn't figure out! Thanks!

When I'm building my spacecraft and I decide to change the command pod, the very first piece of all, if I delete it the rest of the spacecraft turns red (invalid) and I can't do anything, even if I add another command pod, I can't couple it. Is this a bug or has a solution?
