Players may see issues with
1. Logging into the game
2. Purchases chests for gold
3. Receiving rewards for the weekend event
4. Possibly other issues, but the above are the main ones

This is a problem with AWS which we are monitoring closely. Hopefully the issues will be resolved asap, but it is out of our control.
Once the problems are fixed then there should be no issues logging in, any chests purchased will be automatically added to your inventories, and any chests won in the recent event will be added to your inventories.

However please be patient as it may take time for the servers to go through the backlog of rewards.

Thank you for your patience
