Edit 2: This issue should now be resolved. Thanks for your patience, and enjoy Winterfest!
We're aware that players are crashing when going to claim their Winterfest keys and are working on a fix right now. We hope to have the issue resolved in the very near future. We'll let you know when this is fixed.
Edit 1: No need to post your error codes, we already know what's going on. Thanks!
