I tried with Chrome 75 and with Firefox 67.
I tried on different computers running Windows 10 and Linux (Ubuntu 19.04).
I tried clearing the cache of these browsers.
I tried everything I could to access my account, but I always get the same error when the game is loading:
This has been going on for several hours and soon it will be the next day in the game, meaning that I will lose all bonuses of the day.
If this bug is not fixed soon, then I will also lose my shield, my troops, my resources... including some that I had saved when I bought a pack.
