for non linear FF branch of FD the costs on non-blocking link segments vary with flow, but now costs are not updated on non-blocking link segments (because not needed for fixed path set or linear FF branch).
FIX: update costs on all link segments each iteration for generating new paths (but do not mark all those links for tracking necessarily)
Start by creating a test project to be able to easily validate this goes correctly
