The Mighty Condor

Was wondering if anyone else was encountering this bug/ glitch. After launching a Saturn V styled rocket, reaching the destination, doing the Kerbal thing and returning to orbit I will find the MK1-3 Command Pod RCS showing its discharge visual effects. The MK1-3 Command Pod is unmanned and no probe. Not actually using monopropellant either, just showing the visual effects. When I dock the vessels, I am unable to save the game or exit using the UI. I can F9 to reload a previous quick save or force close (ALT-F4). I am unable to switch vessels from the map viewer or return to the KSC using the UI above the altimeter. Even returning to Kerbin and trying the "Recover Vessel" does nothing. I have experienced this bug/ glitch around both the Mun and Minimus. Anyone else experiencing this issue?

I just loaded KSP back up after installing the TAC Fuel Blancer v 2.4.1008 and everything is working including the highlight function!

I can testify that I'm in the same boat. I don't have TAC re-installed as KSP did something funky a few days ago and I had to wipe everything and re-install all my mods but when I had it the only issue I had was it would not highlight what component I was trying to action. Balancing and transferring all worked perfectly.
