There's a weird box around kerbin when using EVE (both the overhaul and 7-4). I deleted EVE and it's no longer there. Does anybody recognize this bug? http://imgur.com/oq7dWRp

Actually... Upgraded plasma thrusters can use the quantum vacuum as fuel, you just need to switch to that from anything else once you have unlocked the upgrade (and have enough power). Also, you don't need onboard propellant for the upgraded thermal turbojet either, you just need some air intakes and a reactor (or a microwave thermal receiver).
