Hangarback Walker not creating thopters after latest update
I am seeing the same thing. If Walker is destroyed, the eight thopters are created, but none are created when three or more gems are matched.
Edited to note that it looks like this is fixed now. Thank you!
There seems to be an issue with effects from gem matching. Cards and pw abilities.
