I had originally posted this topic as a request for one of the above locations, but Shiro has mentioned the Team will be looking and working on the missing ones.
Since I could not remove the whole topic, I am editing the post and making it a reference list for possible issues.
Thank you, Slowly team, for all the nice stamps.
