What you were expecting to happen, and what actually happened:
I was expecting the game not to freeze
How often does this happen? When did it begin happening?
The bug is 100% reproductible and can happen in any game mode. It can also be triggered defensively but with a low odd though.
Steps to make it happen again
When casting The Flame Soul with an upgrade 7 or higher, if the selected gem (red) is destroyed due to the 7th upgrade which destroy 3 random red gems the game will freeze. You can reproduce the bug with 100% accuracy if there are only 3 red gems or less on the board.
This is very specific and I know @Kafka heard about it in the beginning of october without all the details but since this exploit is now used in GW defense teams (probably not on purpose though) it should be adressed.
