Problem with Player.img (Grand Theft Auto: San Andreas)

A funny bug happened:
• I replace the standard player.img with another one, I go into the game and notice that it has not been replaced. (o_o)
• Editing some textures, I go into the game textures have been replaced. (0_o)
• I delete plaer.img from the game folder using a new player.img, I go into the game and again player.img is not replaced, but the replaced textures are preserved (0_0)
• I do the same, but I just empty the basket, the result without changes. (O_O)
• I delete player.img from the game folder altogether, the game still works with the old player.img. (• o •)

How can this be?
