Index credit bug high risk

[AlphaSpeedy]

Hi DE, hi Tennos!

The calculation of the credit booster in index missions with high risk is wrong:

I've started the first mission of the day and made 3 rounds, result:
3x 250,000 credits + 450,000 boosted credits = 1,200,000 credits. Only 450,000 boosted credits? The boosted credits should be:
( 3 x 250,000 - 50,000 {investment} ) = 700,000! And what about the 1st mission of the day bonus? 

After that I've started the 2nd mission of the day with medium risk and 3 rounds to see what will be the result:
3 x 175,000 credits + 485,000 boosted credits = 1,010,000 credits. I think,that's ok:
(3 x 175,000 - 40,000 {investment} ) = 485,000.

Long story short: Obviously, this is a bug. Why are the boosted credits with medium risk higher than the boosted credits with high risk?
