@KuroYokai Your workaround is working like a charm, thank you very much! Making a backup of my save files and off we go!

Thank you, glad to be here with fellow Kerbonauts! Yes, I am using 1.6. I just wanted to attract the attention to this specific issue. Thanks for the quick response.

I am having an issue with the LV-N "Nerv" Atomic Rocket Motor in VAB and SPH on a fresh install with only latest MM installed. The engine appears to be running (with flame animation) in SPH an VAB and also does not appear in the staging column as a selectable part. Also the delta-V does not show for said engines. When going to launch site, the engines appear in the staging column and can be arranged but it is still annoying to have this bug while building. Reproduced the bug on two different computers with fresh KSP installs and only newest MM installed.
