I'm a little worried about the negative levels converting to HD still, actually at the moment. First, we might want to say that "permanent" negative levels are really HD advancement. Next, when do negative levels normally expire? If they just last forever unless these things get a positive level, I think any negative level will become permanent (because the negative level will always last a week). So, solutions could either be: negative levels last a couple of days but can be "renewed" or negative levels have to last 2 weeks before becoming permanent. Thoughts?
