Missing TA funds

half a year ago I've got that bonus, but now - didn't

I guess you mean this bonus. The "Bonus" is just a Math-Calculation. You could buy with the smallest packages 90.000 Funds (22.5 times 4000 Funds). This would be much more expensive. Compared to that you got 66% more Funds for same money.

Hey SRVR​,
