So they actually kept the "You won't get ZTQ-15 parts in ZTQ-15 crates" mechanics even when buying crates for real money.
That's scummy even for game industry. EA or Activision would be proud.
e: just checked the event text, it says This vehicle is available via Loot Crates, which drop ZTQ-15 parts. However, it turns out it they do not actually always drop that.
