Mission Pass Season 8 - can't buy tiers?

Hi all,

I was under the impression that I could purchase tiers for Mission Pass, and I was intending to do that to complete my Mission Pass 30/30 (I was on 27). However, after the maintenance, it seems that my pass is locked - right before the eternistone that I've been grinding for with premium.

Is there anything I can do to fix this issue? I have over 2000 star gems so that is not an issue, I just want to get the stone that I have been working on for a month.

Best, Leviathan (Ship 1)

after the maintenance is not possible to raise the level of older mission pass, is only possible to buy levels while the mission pass is still active but after that the only thing you can do is get the rewards you didn't claimed yet
