I’m not sure what you mean. T112461 was specifically an issue where sources were not linked because the format did not match the expected one − combination of protocol-relative URLs, expected bits ?useskin= which were not there anymore (possibly following the pywikibot upgrade ? never really checked) − and I fixed it last month.
A different issue is that fields in the database are limited to a certain size, and when source links are too long they get truncated − if you look at the link in the monument you sent, it is cut way before reaching the oldid. This issue is tracked at T112460.
