Can you identify these film spots?

I shot a roll of Kodak Portra 800 with my medium format camera earlier this week and developed it myself the other day. On the last image of the roll, I noticed there were a bunch of brownish blotches all over the image. I've never experienced this before.

Does anyone know what caused this?

This is the only image that was heavily affected. The two preceding it have a couple much smaller, lighter blotches.

The only thing that didn't go right while developing was that, while it was in the black bag, the take-up reel I was winding it on to came apart and the whole roll came undone, causing the negatives to touch each other as well as some sweat from my hands as I tried to fix the take-up reel.

Thanks!

The film was in direct contact with the film under it in the spool.

Wrong way of loading film would cause uneven development (like semi-transparent stripe on the bottom). No-see-through-spots happen because of not getting solution at all. It may happen because film was loaded improperly, leaving no way solution could get into. Still, it's very interesting, because spots do not happen this way. I experienced only streaks of that very kind of situatuion, not spots.

Maybe you poorly agitated film drum, while there was contamination of developer (it was too weak and agitation was insufficient). Sweat would leave overdeveloped (contrasty) spots, while not preventing development at all (brown spots). The only easy guess I could make is that smth like drops glue fell on emulsion which prevented development at all. That's perfect match but not quite probable)).
