Need help, this is bug or whaa?

[StonedRhino]

This happens when i make a small change or large change to the engine(I cannot see the prevois curve compared to the one being laid down).
This leads me to the question should I be able to see the previous curve? Im sure i could before. Its much harder to improve an engine when I cant see the previous curve.
Also, If i am not able to see the previous curve, does this mean that the part of the curve i can see is the only part which has changed?

Are either of the engines failing during the run? That's the only thing I can think of, if not it'd say it's a bug

[StonedRhino]

no the engines are not failing + i reinstalled the game, Loaded an engine and run it without any changes and this is problem(But it also happens when I create a brand new engine)
After i reinstalled i saw the prevoius curve once, since then had this problem again

I think this comes from when the graph rescales between runs, and yes, it is a bug that I have seen too. Not a top priority right now, but needs to be fixed eventually.
