Allow Flash even after browser close (Chrome 69)
As the devs have told us, Chrome 69 forces us to once again approve flash every time we login to the game.
There is a "permanent" (at least until Chrome changes something else) fix for this.
In your address bar type "chrome://flags" and hit enter. Then search for Flash. Find the setting "Enable Ephemeral Flash Permissions" and disable it. That will preserve your flash settings and permissions after you have closed your browser window.
Hope this helps!
