Of course it had to happen with 3 rolls from an important wedding! Rollei 400S retro... XTOL 1:3 @ 20 degrees for 17 minutes.... Stop, fixer, wash as usual... negs came out totally clear. Nothing. Why me? I must have been really bad in another life ;-) All my other films (35 and 120) have been perfect (mostly TMAX). I must say I was surprised at 17 minutes but that's what my iPhone digital truth app said! Agghhh!
