It looks like the timestamps of when individual members signed up for a raid are disappearing. It doesn't happen all at once either: right now we have a raid where only the oldest sign ups have had their timestamp dropped. Is this a feature that I just can't make sense of or is it a bug?
Hmm, how odd: now that I look at things from my home computer, all the data is there. Same browser (FF 1.0.5.7) and OS (XP SP2). I know specifically the raid on 11/24 was missing dates before. Browser caching problem maybe?
