Super Snake Block DX

This is snake nr. 17, the one just before the one with the guy riding it- but this achievement glitched two times for me, so i even had to delete my save. I figured out that entering/leaving the snake menu can glitch out the numbers of your snake, for example i managed that ALL my snakes are labeled as nr. 19, which is needless to say totally wrong. I collected 200 coins, restarted the game and made sure the locomotive was labeled as nr. 17, bought it and the achievement unlocked. I'm not 100% sure, but my advice is to restart the game before buying this one or simply make sure the number is correct. I hope this helps somebody.
