Hey, so I've recently bought Praktica TL3 and I've gone through two rolls of film, both of them with 36 exposures. Unfortunately, in both cases the last photographs are always missing which is quite sad as I remember I was proud of those shots.

I use minimal amount of film to wrap it around when I first put it in, I don't think I leave empty frames (even if I did, the counter would count it as a photo), I don't go over the 36 on the counter (and I wouldn't be able to as I couldn't rewind anymore, the lever is stuck when the end of film is reached). I wouldn't mind if it was 1-2 but I'm pretty sure there are almost 10 missing and the ones I was anticipating the most.

Do you have any pieces of advice on why that could be and how to avoid it? Could it be a problem with the camera?

Thanks a lot for your help.
