I think if you've been holding onto a "On-Hold" slot for some arbitrary amount of time that depends on how I'm feeling at the time, I'll reinsert people 3 games down the queue at request rather than having their game run next or something.
As for people that fail to ready up even after being reinserted into the queue, so I'm basically thinking of people that say that they'll reenter the queue except they don't actually have their setup properly prepared yet and hoped to finish it in between games, I'll probably just drop them back to the back of the queue.
Because I mean, to be honest, disruptions to the mod queue are pretty annoying. Especially so when it's because the setup isn't ready and you generally have over a year to get it ready upon entering the queue. And then it puts pressure on the people immediately after you to be ready etc. etc.
I mean I'll think up a proper way to deal with it eventually but for now I'm open to ideas and whatnot.
