if you ever go to import and drop a map image on the token layer it by default seems to start at exactly one square size no matter how many pixels it is, and on the map layer it is 3x3 no ,matter how many pixels it is , but the blue size adjustment boxes along the sides are the same on both layers. If you have to stretch by these tiny blue corner and middle boxes that can be hard to grab if you are zoomed out so you have to zoom in again to see and click them, if you zoom in far enough to click them then you cant make it bigger than your zoomed in screen and have to stop then zoom out a little , try to grab them again to fill that much of the screen. then zoom out more and try again . if you are uploading during a game this can take a min that all the players have to wait and it slows your game down. it would be nice if on the map layer the blue stretch boxes were always bigger and easier to grab than on the token layer and got bigger the bigger the image is. This might have been fixed but is still in Legacy games.
