Can anyone figure out how to make the coffers rank up, because we got rank 4 coffers on 5/5/x twice, made great money (and gear), and then on our next four runs we got no rank ups on the coffers and lost millions.

If this mechanic can't be figured out, then I'm probably done doing anything besides 1/1/1 for Bayld, as 5/5/x runs are far too expensive to lose money attempting fruitlessly.

Thanks!
