I'm unsure if this is a bug with KER or if there's something else going on, but while using KER 1.0.17.0 and flying any air-breathing vessels in Kerbin's atmosphere, the "Intake Air (usage)" entry in the Flight Engineer/Vessel panel always reads as 0.00% regardless of what altitude I fly at, what throttle setting I'm at, or how much Intake Air KSP's UI says my craft has. I posted a thread in Steam's KSP forum, but no one commented after two days, so I thought I'd post here to see if I'm alone with the issue or if something broke moving from 1.0.16.6 to 1.0.17.1. KER is the only mod I installed after cleanly installing KSP last week. I had KER 1.0.16.6 previous to upgrading to 1.0.17.1. My game license is linked to Steam, and I let it update KSP for me.
