Within the Pokémon games, there are various examples of instances where the collision data of tiles have not been sufficiently coded. As such, a player may be able to walk on to a tile that was not intended to be stepped on by the game developers. Also, a player may be blocked by a tile that he or she usually has the ability to walk on.
Other problems are often caused by objects or events which serve a purpose in changing the player's map coordinate, for example in the first generation of hand-held Pokémon games, if the player jumps off a ledge and an NPC is in the position that the player will land, this will give the player character's sprite a higher priority over the NPC's sprite, making it appear as if the player is standing on top of that NPC.
