As some of you have already noticed, Wargaming is currently facing an issue with the Frontline progression system. The experience values displayed in-game required to reach the different Tiers are incorrect.
Wargaming is going to deploy a micropatch to fix the issue on 10 March at 03:00 CET (UTC+1).
Afterwards, Frontline progression values will be displayed correctly and all the already earned Frontline XP will be converted as per the correct values.
Due to the update, servers will be unavailable for 45 minutes.
