Hi guys

Do you have an issue with multi battle whereby only 1 champion is selected to a battle even though 4 is selected?

Happens if all your selected characters are max level... auto battle feature will kick out all max level not in the leader spot... really makes the feature kind of useless tbh. The feature shouldn't be usable only for farming food levels... But it seems that's what Plarium thinks it should be. Kind of one-sided approach and not really helping in pushing user-satisfaction. Not to mention the restriction on how often it can be used...

Adjusted the Multi-Battle Champion queue to make it more convenient for the players

This is probably the culprit. Max lvl non-leaders got kicked before but only if you'd set them in the queue.
