I have lowered the work buffer size from 4 to 3 days as the time estimations for the work units became way to short after lots of Type C's finishing after 25 minutes rather than 5 hours (without error results).
If i had set a 9 days buffer, i would have now approx. 14 days of work downloaded. Better keep it low folks :)

Another dg03 Type A quit with an error. All of the dg03/04 Type A WU that I've received have quit with errors.

I'm pretty sure that none of us badge hunters would mind if you sent every batch through beta testing first...

Same here, not had any new WUs for last few days.
