When I did FMCB's multi-install for the first time, I think I had corrupt icons on my MC but FMCB still worked fine. I deleted them, redid FMCB's multi-install process and now I don't have them and FMCB is still working fine. Shouldn't I always have corrupt icons on the MC after doing FMCB's multi-install since it supposedly always corrupts the MCs?
