b31 - White circular foxes

[TheRani]

Sometimes when I fight a fox, it displays as a white circle instead of the normal fox tile.

After I saved and reloaded, the fox displays normally.

Had this sort of thing happen to me quite often, seems to be more prevalent when I die and restart a new character.

White tile replacing tile for both critters and items (iron helms/cloaks)
