https://xcraft.net/forum/topic_33323Victoria, I had switched it off early that day, but switched it back on. And then checked to make sure it was on.
As stein said, it's a problem with the browser, not the game, but that still doesn't make it my fault and I unfairly lost fleet due to this glitch.
So, don't say " It is not a bug " because it is a bug, just not with this game, with the browser. Yet the bug still affects the game, so it's still a problem.
