[15.5] Can not unfollow failed achievement

[emerlaus]

i follow a achievement and i fail it and i can't unfollow it.

I'm not quite sure about this workaround, but I belive following an achievment is set in general. So you should be able to start a new game and unfollow the (not failed yet) achievment and you're okay.

Could not reproduce, I can unfollow failed achievements with no problems. If this is still happening, please post log and steps to reproduce.
