I’ve been having an issue lately where if I am awarded a pack, for example arena daily win. Every third pack I get in one session crashed the game. For example daily war zone, daily arena and rank up req. The game would crash as I open the rank up req.
This has been an issue for many people, including myself. I know no known fix, sorry. You don’t lose any of the requisitions though, they should still be in your collection.
Many people are having similar problems. Hopefully 343 will address them.
I hope they do, it’s not the biggest issue but it’s still annoying that the game crashes and I have to restart it especially if it’s a game night with friends.
