Hasn't seen it happen again. Thanks for fixing!
Edit: Also, the balance tweaks are pretty good. Not as many golden weapon drops at earlier levels means no more just cruising through all levels with just any tier 2-3 units. Also noticed late 5-x and 6-x levels seem to now depend a little on the luck of AI (both us and them) positioning and targeting but not so much on initial positioning. Putting the entire team in a cluster and just letting them target randomly somehow works better than spreading units out to include preferred targets within attack range.
