#7996 Bug: Two-part artifact links don't work after a ticket move
A good sample can be found at https://sourceforge.net/p/open-cobol/feature-requests/86/ as it includes two of them with exactly the same format (only the artifact number differs). One artifact link works (replaced by a link, adds to "Related"), the other artifact link does not.
Issue seems to be related to moving tickets. See https://sourceforge.net/p/forge/site-support/11353/#718d for detailed reproduction steps.
As it's clear that this is a bug and the steps to reproduce are there (ignore the status "self-service" of the linked forge ticket as it mainly says "dont' use two-part artifact links as workaround"): Will you assign any milestone (=plan two fix this)?
