Nope, no reward glitch as far as I can tell.  I had some miners go down on my rigs in the past 18 hours or so, so several percentage of the payout went back into the pool that I would normally get at my hashrate.  Scoring in action

1984 - how much do you think you should have gotten?  As in, how low is it compared to what you were expecting?

Our hashrate was down to 50 GH/s or so from 80+, so those people that dropped out should have boosted everyone elses reward compared to prop.
