I know that some console commands cancel achievements while others like checking evolution do not.

What I don't know is if changing the game speed cancels them? I would think not, as it will just make playing harder. However, I am in late game with over 48 hours invested and in a stable safe place on the hardest map possible. I want to get this game over with, but do not want to mess up my achievements as this is the hardest vanilla game I've ever even seen be attempted. I am recording this play through to post on YouTube. So soon you can check it out.

I would be most appreciative if anyone knows this answer for certain. Thanks in advance.

Yes and you will get a warning when trying a command for the first time.

Commands in the Scripting and cheat commands table will disable achievements when used. As changing the game speed requires use of the /c command from that table, yes, it will disable your achievements.

Edit: And as Loewchen mentioned, any command that can disable achievements will not execute and warn you on first attempt. Trying the same command again will then be executed and disable achievements.

Thank you so much for the information!
