Noticed this since last maintenance (18th April now). It's ok (well, normal, so ok-ish) before I invite another player into my adventure, but really really annoying once I do. It takes approx 7-15 sec. before a general shows it's been emptied out, or loaded up again for the next attack. And sometimes it even reverts back to the troops it had equipped before, so I need to triple check everything. Am on Chrome browser on iMac, dont know if that makes a difference.
Hope BB reads this and fixes it soon!
