Check your AR202 case. It can be placed in different orientation. Game always uses AR202 by default to control your craft. You can also check if your command module is selected by "control from here"

Thank you very much, it totally works now!

Umm... Is building rockets out of nothing intended? I use the new launchpad (the one with engines) and i can build anything without even having enough resources. Everything is fuelled and ready to go. It is the way it should be, or it only subtracts resources if available and build rockets anyway?

Well, removing MJ2 solves the problem on clean save. Savegame, where MJ2 was used and removed later, the problem persists. Maybe MJ2 writes something in the save config, or somewhere else. I'm just hoping this little bit of info helps.

I would like to get your attention to the plugin incompatibility. MechJeb2 has one nasty bug, if used with Kethane Mod 0.7.4 After using quickload, Kethane grid map stutters and game becomes pretty much unplayable, beacuse camera in the map view stutters as hell. It is already confirmed, that MJ2 causes that. As for me, i totally love MJ2 and used it for a long time. It pains me to remove such a nice plugin. Is there anything you could possibly do to fix that? Here's the link to the kethane mod thread: http://forum.kerbalspaceprogram.com/showthread.php/23979-Kethane-Pack-0-4-3-Download-link-now-up-to-date-after-forum-catastrophe

I can confirm that MJ2 is to blame. Curiously it has to do something with savegame too, because after removing, clean new savegame work perfectly, i cannot reproduce stuttering. And the old savegame still experiences the bug, even with MJ2 removed (and vessels with AR202 part being deleted too). I got clean steam version with only Kethane and MJ2 plugins. Shame. I was never too good in orbital and interplanetary transitions, leave alone landing...
