This bug is still present with [.91]. Another related bug occurs when movement is queued to attack say a bandit at a camp, but the bandit attacks first, then army moves onto bandit camp without collecting good. Have to leave and comeback to get the goodies.
Another time this co-location occured is when I moved onto an empty bear camp, but a Bear Army spawns just as I arrived. No battle and No goodie pick-up. Each time this occurs is when the movement was queued to happen when I ended the turn.
