Since its launch, Pokemon Go has suffered from two major flaws. Firstly, its servers are prone to crash at the drop of a hat which, aside from being irritating, is also costing players money as items such as lures and incense only work for a limited period of time - if you drop a lure at a Pokestop and then the game's servers go down, the game won't return that lure to your inventory even though you won't be able to make use of it. Secondly, the game frequently crashes after throwing a Pokeball at a Pokemon, meaning that players have often found themselves squaring off against a rare find, only to have it escape as a result of the game freezing.
Now a new problem has presented itself, with the game's tracker failing to correctly display the distance between the player and the Pokemon they are hunting. When working correctly, the tracker displays the distance of Pokemon using "footprints," with one footprint indicating that the Pokemon they're looking for is close, while three footprints indicates that it is a reasonable distance away. However, a recent issue with the tracker has seen all Pokemon marked with a distance of three footprints, thus completely undermining the entire concept of the game.
