If you are in a house and try to open the map, the game shows you the beyond “maps reach screen”. This works for the majority of the game, but when you get to the point that the pestilence shows up it gets interesting. The purple highlighted areas can be seen on it, they are mirrored though. This seems like it’s unintentional.
If the player opens the map while in the Dusty Loom, it displays as “BEYOND MAP’S REACH” which maybe itself be a bug, since opening the map from other indoor areas (War Room, player house) still displays the map normally.
However, in addition to that, if the player opens the map while in the tavern, then leaves and opens it again, the icons of the characters in Sacrament are displayed at a very large size.
