There’s already a topic regarding this in the regular MCC forum, so I I’m making this here since this is a bug. Hopefully to get the attention of MCC’s support team.
For some reason, the Chrononaut challenge isn’t unlocking for me. I’ve completed 2 cross game playlists and neither of them unlocked the challenge. One thing to note is I played through both of them for the first time. I don’t know if it will only unlock if you play a playlist you’ve already completed. I submitted a support ticket for this but I’ve yet to get an acknowledgement from the support team. Its extremely frustrating, because I’ve only seen very few people reporting this problem… Making the situation worse because it won’t be a priority for 343 to fix it since it only affects a few people.
Super… I can’t unlock content in the game for a reason that is completely not my fault.
