I can't find bug report. But

I have just come back to the game and found my PZ.IV E “Ghost Division” is gone and went back to the shop. I bought it a couple months ago with my gold order, why is it gone?

Have u tried checking every tank squad u have since it could be on a different tank squad ?

Yep, it’s gone

If you are sure then please use

and inform them about your missing items.

It won’t let me report, I can’t find my client version either.

I tried, I’m on console and my TV cuts out the client version. I am quite literally unable to fill out one field and it’s preventing me from reporting this issue.

How do I do so? Forgive me, but the link leads to articles but no way to report.

It’s not report but it’s Customer Support they should be able to help u get your item back.

Got the request submitted, thank you.
