Opened all 135 of my Nier crates that I was saving for the battlepass pass xp and nothing happened, assumed it was a weird one off bug but after playing for an hour it's still stuck at tier 5 (I used bp level up cards to get it to level 5).
Super annoying considering that they're definitely not gonna give me back the 135,000 bp xp that just apparently all went into the void when this is eventually resolved.
