Talk:Now or Never/@comment-2601:40B:8503:11A2:B122:F9F5:94FB:1279-20171120155942/@comment-79.121.84.143-20171120171631

What do you mean exactly? The quest should start as soon as you complete A Matter of Life and Death and A Favor for Radovid. Doing the previous quests already listed in the description will lead to Now or Never. It fails if not completed until The Isle of Mists.

This quest is also a part of Brothers in Arms: Novigrad, but you still need to complete the other two it depends on first. Another possible problem is that the Radovid quest chain can be broken by the use of fast travel mods to leave Whoreson Jr.'s estate in Get Junior.
