Hm. It was 7,000 before. After you purchased the Tier 2 frame for 7,500 Crystite, did you go to the Battleframe Station?
All tier 2 frames have the same equipment as tier 1. Basically you're weaker than a maxed tier 1 frame unless you gradually unlock new equipment and better abilities in tier 2. Crafting is also available starting in tier 2.
This is bad progression and it is acknowledged by Red5. They're going to fix it.

The devs are back in business today at the office so I'm hoping for an update soon of what they are working on.

The bug occurred for me in Tier 1, and I did. I had to grind out 1k Crystite on no knowledge of the game because the server bugged out on me right when I went to purchase the second Battleframe as part of the early portion of it. It never registered the existence of the new frame, even though I had everything for it. The next day, I still didn't have the frame in my list, so I rebought it and it worked then.

There's also a bug where it takes a long time to notice that you got a new frame unlocked. When I unlocked the Rhino frame, it took like 30 minutes for me to be able to purchase it.
