Additional info to Beee`s post: when you pull those adds which did not despawn, and you pull the named as well, he applies the detrimental which you get in the solo-zone if you have killed the first one: you only have 15s left to kill the next one or to click the appropriate brazier or you wipe. This won`t happen if you just kill the non-depopped adds without adding the named - BUT I guess since Chrol will get that despawn fixed it shouldn`t matter! Just letting you know, Chrol!"
The 15 second timer being applied during the 4 add stage is a separate bug that's already fixed for tomorrow's launch.
