If the owner of the site reads this, I'm unfamiliar with your project but I've spent my career untangling especially tricky problems of the kind you're describing. If I'm being honest I find it to be fun. Based on upvotes this is clearly a project some people cared about. If you would like, comment and I'll add a way of contacting me and do free consulting to take a look and see if I can fix it. I can't make any promises but from what you described it sounds savable.
