supersara2001, from what I understand, you have some yellow spots on the film.
Refixare and rewashing operations are never bad.
After me, the yellow dots that you know the film appeared to be thiosulphate decomposition in sulfite and colloidal sulfur.
Those particles can be colloidal sulfur yellow.
Washing with water and use to end substance that reduce surface tension
can do better.
Filter the fixer solution or replace.
