[2019] The High School Fleet Won't Wait!

They have an expiration date, it's just unfortunately the client doesn't display them for challenges, only for combat missions.

Isoroku was awarded for combat mission, currently he's not available for obtaining. Unsinkable Sam got jealous and we don't want a catfight on the decks ;)

I can confirm, if you unlock that collection — it stays with you forever, even after collaboration ends, so you can finish it at any date, no need to hurry.

How many battles you have played? If less than 70 battles — they you don't have access to combat missions yet :( The missions are waiting for you in that section (the button will appear in the port on the left side) Shouldn't take long if you can find time to play on weekend.

I've checked — you actually have TWO Thea Kreutzer in your reserves, one has specialization for Dresden and another for HSF Graf Spee

Can you recheck carefully please? Scroll the list to the end, maybe she's displayed in the wrong order. If you can't figure it out — consider PMing me a screenshot of your reserves.

That's true. He didn't say "ONLY" HSF commanders.

HSF Spee can be helmed by HSF commanders OR German commanders.

HSF Harekaze can be helmed by HSF commanders or Japanese commanders.

It's also possible you've disabled displaying of HSF content, so you've seen her with a regular name and portrait, please check that as well when you get into the game!

If you can't figure it out — tell me :)
