The Bypass
So you (probably) already know that achievements are broken. Some are impossible to get, and others you get when you should have gotten a different achievement. My solution is to use SAM (Steam Achievement Manager)[github.com] to GIVE yourself achievements that you SHOULD have, and REMOVE achievements that you SHOULD NOT have. BUT PLEASE DONT USE THIS TO GIVE YOURSELF ACHIEVEMENTS THAT YOU SHOULD NOT HAVE!!!!!!!
Until the achievements are fixed this is the only solution to this issue that i know of.
