I sync my Facebook events with iCal and like to have previous events stay in there as a record of what I've done in the past. They now seem to disappear after they occur. I think there used to be a setting somewhere in advanced to fix this but can't find it, and haven't had any luck searching forums. Anyone know?
I seem to have fixed this by deleting the Facebook calendar feed I had (which just showed facebook events with a blue dot), and replacing it with the "built in" Facebook account calender (which shows events with a blue F next to them and seems to show past ones as well).
