Finished monthlys but no reward chest
Probably because they are about to be updated … And made non existent
No, because they wrote this in their update about the new system:
“Because some of you have already made progress on your monthlies, we will leave them in for this final month, allowing you to earn bonus laurels.”
So I would expect them to give the rewards based on that.
Did you possibly have a queue of unopened chests wiggling down in the corner? If so, your Monthly Reward Chest may have been automatically opened. Sure you completed all tiers in each category?
If you check your inventory and/or totals and find no reward, you can contact the CS Team for assistance. Top of Page – Support – Submit a Request.
Good luck.
