So I've been just getting into developing my own and yesterday I lost 1 and a half films and then figured out it was somehow related to my changing bag.
See the problem is that it gets either too hot or too humid with my hands in there and it makes the film jam up really bad ..REALLY BAD! I thought it was my film and after an hour of trying and re-trying I decided to sacrifice one of the rolls because it was too sticky and wouldn't go onto the reel more than a few inches.
Pulling it out of the changing bag and trying the SAME film in the light where I could see what I was doing it went on first crack!
At first I thought it was my technique, so practiced practiced and practiced some more then tried my other roll that I had and the same thing happened! So I got someone who had developed their own film before (albeit not that often and never in a change bag) to do it for me and they said they couldn't do it and that using a bag was alot harder than the usual DARKROOM method they had used before.
I ended up quickly building a darkroom in my closet. too the bag and contents in there, removed everything from the bag in the dark and it rolled onto the reel first crack!
Anyone else have issues like this? I'm using 120 film and have several different reels that all performed similarly under the given conditions. Grrrrr
