Unreachable gold in TFT

Sometimes you can get gold dropped from the Boxes in Minionwaves, but i once had a problem (as seen in the picture) with the gold flying off to an area unreachable for my Avatar, so the Gold just sits there until u either die or win, its nothing gamebreaking, but i guess it can be annoying when this happens. Things like these aren´t really that bad, nor am i upset that it happened to me. Things like these happen in a game which is still young. I would suggest that either gold shouldn´t be able to spawn outside areas which are not accessible, or just make the area accessible, because i dont think gold will ever spawn on the other side of the river :D.
