There are two different issues though if I'm correct, as 2 topics have been merged here. The one you mentioned, and another one affecting Eroges and the test server, as far as I know.
I still don't have any league, and haven't received my rewards from the previous league. Considering it's past office hours in Sofia, it's safe to assume that leagues won't be fixed before monday at best. That redeem code is not even close from compensating the missing rewards from last week, the missing xp from this week and possibly missing rewards if it isn't fixed at all.
On Eroges, based on what I've heard from my club and on Discord, this issue seems to have only affected players that finished Top 15 in last week's league.
