Been poking around and have seen other people with the same issue, but have yet to see a fix so point me in the right direction if there is...
After about 10 games or so (on steam) I start to get a bit of lag stutter/lag that keeps growing from every game there after. It gets so bad the dropping gems and animations just either skip or pop up and disappear.
It seems to happen more often when I'm grinding as quick as I can like explores for this weeks event.
**Quick edit, restarting fixes it fine on steam or android.
