When you have a T1 engie assisting a T3 air factory that's building ASF (aeon) it shows (if you use the economy overlay) that it uses 0.6 mass/tick and 66 energy.
However, if you click the engi it shows in the bottom left that it uses 66 energy. Mass draw is not shown. Of course that engi does draw mass. The T3 engi shows 4.7 mass and in the bottom only 4
I've had a few games where multiple people in my team of 4 were berating me for using support factories, claiming that "T1 engies don't use mass when assisting for ASF". That included some 1000 rated players.
So can we please either show the decimal cost in the bottom, or at least round it up to the nearest integer? So that perhaps these very strange people will finally stop spamming 500 T1 engies to build air?
