Didn't see any solution for this, not anywhere, so I'm posting in the hopes that somebody sees this and found a solution in the three years since the problem was stated. I have tried to deactivate every function of the trainer, without result. I have tried dying, with no function of the trainer on, without result. I've tried to try it without the trainer running at all, both shutting it off while in the game and starting the game without the trainer, also without result. I still cannot buy the armor and I would really, really, like to have the complete tattau. So any other possible solutions, or a confirmed one would be highly appreciated.
