Thank you for giving some insight from what you have experienced. I read that grouping events will add extra cpu usage, so I avoided utilizing that feature, but I'll consider your suggestion.
Ah that a little strange when you arranged board in square or rectangle fashion and the game isn't playable. The simple work around is by putting a 'peg' over a pad (just only one) in that kind board arrangement. I'll Investigate this, because the problem was not exist in previous update and any board layout should be fine anyway.
