Fiancee and I had the same issue, except that when we opened the floppy on the pc it was empty.
Kerfur-O had not gotten any reports, just ran off with it :/
Viewing post in 0.90 Server Reports with my Kerfur O
Kerfur seems to be a bit buggy in this update. I haven't had the same issue, but my Kerfur-O has gotten stuck in a lot of places that it didn't in previous updates (under satellite dish stairs, right next to the river, etc.), and when I get Kerfur unstuck they just start the entire report process over again or worse, they cancel it and the floppy disk is just gone.
Hope these issues get ironed out.
