After purchasing efficiency upgrade of vehicles my automobile per Km cost has increased to 0.35 from 0.05 earlier, even after it was mentioned to reduce 30 percent cost.
It seems to be correct looking at what you have set up. The zeros bay be confusing you somewhat. 0.05 vs 0.5
Please look at the figure of Automobile
It was before 0.05 per Km That has increased to 0.35 per Km.
Which is almost 700% Increase instead of 30% decrease.
The effective cost after reduction should be 0.035 per Km instead of 0.35 per Km.
I hope I made my point clear.
That helps. We are investigating. And it is likely just a display error that does not affect your prices.
