When a tree is close to the top of the viewable area, and I pet, water, or feed it, the response dialog is placed too high. Can't read all of it because it's outside the viewable area.
Example: there's a fruit tree on Groddle Forest Junction between the Herring Bone Hatch and West Hechey Clearing signposts.
