On my A12 magazine the film advance indicator (on the roll holder key) is stuck. When turning the key to take out the roll holder, it does not reset, but stays red. Opticaly this is not a big deal, but does it influence operation in any way? Thus far I do not notice any problems. Frame counter works normally. It is possible though (don't know if it suppose to) to take out the roll holder midfilm. I haven't loaded any film yet, I noticed all this while checking my camera.
