I haven't used the "low-hanging fruit" link in awhile but when I attempted it last night, it displayed incorrectly. It showed one badge five times, then a second one 5 times, etc. for a grand total of 10 badges, instead of 50. I thought it was a weird glitch that would disappear if I logged out and logged back in later.
Today I logged in and the low-hanging fruit function was still misbehaving. I noticed that it would list a badge, say, Wolf Spider Enforcer, badge #131, seven times but the count varied for each entry (showing that 10,643; 10,603; or 10597, etc. people held that badge). So now, instead of 10 badges showing, it's down to 8 (7 badges seven times and one badge once). I didn't notice if the counts varied when this first occured.
