Hello Adventurers,
We have found the cause of the issue - occasionally the game seems to be running a check to make sure there are available matches during the explosion at the start of turn.
This causes a lockup. It is extremely timing-dependent, and on some devices it seems to be quite rare.
This is why it doesn’t happen every time his trait goes off.
We will look to try and get a fix for this issue in the next update.
In the meantime, we are going to change his trait so that he will explode 4 Good Gargoyle Gems when matching 4 or more Gems.
We will have this change out shortly with updated text for the change. I will be hanging around after it goes out in case anything else pops up.
We will look to restore his trait once the fix is live.
