Description

When using --abort-on-error and --abort-on-unavailable-fragment and there is a issue upstream with the availability of the fragments the program does not attempt trying other format options, it only keeps trying the primary one until it aborts the whole process completely.

Shouldn't it try all of the options same way as if the format wouldn't exist, before aborting the whole batch job?
