Issue:
While playing the New Atlantis mission Odin’s Tower, I destroyed an enemy Watch Tower full of enemy villagers and then attacked the next Watch Tower, around which point I got the message “Unable to load because Watch Tower is already full”. It seems like either it was a message for the AI player that accidentally sent to me, or the game mistakenly gave me a message about garrisoning after I targeted the next Watch Tower with my units.
Also, as a side note, the message seems to be worded for transports rather than garrisoning in buildings, because “load” doesn’t make sense for entering a building.
Trigger Event:
I destroyed an enemy Watch Tower full of enemy villagers and then targeted the next Watch Tower. Or possibly I attack-moved.
