Interesting tidbit here.  Please tell me if you've noticed anything similar.
Over the last two days, my elf miner has been pulling unusually high levels of colored ore.  Typically, I am within 1% of the firmly established 75/25 split.  On Sunday, I noticed a 69% level of plain ore - but I only mined 5000 before crashing and thought it was a statistical anomaly.  Today, I mined from server up (31K ore total) and was at 70%...
Did they change/break something unintentionally?  Anyone else seeing deviations from the known?
Best part of today was my massive shadow ore haul...eight percent.  Awesome for BOD running.
