hi , i have the same problem just few seconds ago !

rollei 80s 50 iso in rls 1+4 24c 12.5 min . I believe that is a failure in the composition of the developer in the factory... the rollei film is the agfa aerial film aviphot pan 80 .... and is a wonderful film (in rodinal) .

So film-fix-stop from agfa gavaert (belgium) and developer from rollei (cg 512 formula) ..... it's the developer !
