Achievements Broken

I am an achievement hunter and yes I do agree that some achievements have become obsolete or inactive. But I have never really come across a broken achievement. Just for reference can you provide some examples.

I posted these as a reply to one of comments but if you like more I could go through my list of game and pull a few more out.

The Solus Project: 1 broken achievement.

Cobalt : 1 broken achievement

Warhammer: Chaosbane: 2 broken achievements

Generation Zero: 1 broken achievement

Unbox: Newbie's Adventure: 1 broken achievement.

2Dark: 1 broken achievement

Bloodstained: Ritual of the Night: 1 broken achievement

Mighty No. 9: 1 broken achievement

Rad Rodgers: 1 broken achievement

Yea its true there are broken achievements.... as for how many there? I’m mot sure.... i know the Darksiders2 achievement has been broken for a good while, I’m not too worried about it. But I am curious as to what other ones are broken.... ?

It's not the game that's broken, it's the achievement app that's broken for not displaying it correctly. Are you part of the insider program?

The supplier achievement is still broken :/

I would realy like achievements not to be broken on games release. Defiance 2050 has had broken achievements since July 2018 and nothing has been done to fix this issue. The company Trion/Gamigo have not done anything to fix this. I have also reported
it numerous times to xbox and nothing has been done. This should be a top priority fix for games when they have broken achievements
