Two bug reports, no log necessary unless requested. The first is more of a query than a report, as it could be WAI. Should ~30% CO2 exposure be deadly? If not, then you might want to check up on how CO2 is working when out of power. The second report is about EC again, sorry for reigniting this topic. The dev build fixed the EC bug, but now the game is charging extra EC if you increase the gamespeed. This is not a problem for people with solar panels or generators, as you are gaining more than you are losing due to the multiplication. This is a problem for non-energy generating ships however, even with 9 batteries it makes the trip to the mun cost more energy than you have.
I'm currently up to date with both KSP and TAC (dev .13.4). If I'm simply missing a key mechanic please shout at me, I haven't played around with TAC in several months
