Hello,
Today with the new update, I noticed a new bug as well. When I try to give one of my players rests or morale boosters, the game freezes as soon as I try to give him one booster. (before I can actually confirm it)
It applies only to my iOS device and also only when I'm in the game via Wi-Fi. With mobile data it is possible to give the player boosters, which is very strange... Don't know if I'm the only one having this issue.
