So ever since reloaded took over hawken on their own servers (I think), I've had several mechs (specifically my predator which I did buy and use) say "Test Drive is over..." and I can't use them.
I tried using the ability fix which did fix a few problems with my abilities on my mechs, but didn't fix all of them and there are still mechs with that test drive issue.
What do I do? File a bug report?
