The only issue I found so far is when using the EVA construction feature. When removing a currently attached part, KJR doesn't let go and... well the vessel kinda explodes with the force exerted by your mouse.
It does run on 1.0, but the tech tree nodes needs updating at least. I'm not keeping up with the thread, but from what I've seen an update isn't far. Cheers
Just to notify, other people with this issue had KIS installed and uninstalling it resolved the issue. Also, KIS has been updated to 1.0, resolving the issue as well.
While I have not experienced world destruction, I can confirm EVERY female kerbal flies away when taken out on EVA, and, where I was able to test, duplicate themselves upon trying to reenter a vessel.
