Possibly bugged ERROR 909 achivement?

[CyberBotX]

So, I'm not sure if I've done something wrong in trying to get this achievement. It is in-game achievement 71, ERROR 909. I've turned off my autobuyers for Dimension Boosts, Antimatter Galaxies and 1st Antimatter Dimensions (also technically the one for Big Crunch, but that is more so I can see what is happening), then I entered the challenge that the achievement lists, C2. I buy a single 1st Antimatter Dimension and of course at the stage I'm at (which is after completing IC2) I get to Infinite antimatter pretty much immediately. But when I do a Big Crunch, I do not get the achievement, even though my count for Dimension Boosts and Antimatter Galaxies is at 0. I've also tried doing it in the other challenges (especially C11 which I read was what it used to be on the web version), and still no dice. If anyone has any insight as to what is going on here, I'd appreciate it.

You said you disabled the first dimension autobuyer but did you disable the other dimensions, them producing the first one doesn't count the achievement
Try this:
-Press A (disables all autobuyers)
-Enter C2
-Switch to buy 1
-Buy first dim
-Crunch if you can

Don't forget to press A afterward to enable your autobuyers again

Oh, I see. Yes, that was indeed it, thank you for that pointer!
