Battle Pauseing in cerb and baal?

[Wildflower]

I noticed today when i started Baal i boosted my hero and clicked auto fight. Watched the battle get started then i pulled up another tab to do something else while that was going on auto fight. When i went back to that tab a little later i noticed my guy had not moved or gained any more points on cerb from when i went to the other tab i pulled up.

Is this a glitch in the game or something new that was added for some reason?

Just wondering if anyone else noticed this lately?

Yes, this happens to me in some browsers.
Do all in a new window and don't click them away. They have to stay open in the background to run.
Very odd. Also it doesn't necessarily just pause the animation, it can make you not do banish.
Run it in the background on a seperate window and the issue is solved.
