This is a weird one - I don't even know how I noticed it.
But it looks like...when you go to ping a person, and their post has been previously edited, then you go to preview your post, it says that it has been edited by the person you are going to ping.
This isn't really a big deal - it doesn't do anything negative, and it doesn't carry over to your new post, so it's not too much of anything. It's just kind of interesting to see, and to notice. I don't think it's supposed to be like that?

Examples:




Note: After the first example, I went on random threads in search of edited posts in different forum categories to test if this worked anywhere else. The users in the photos are complicit only by chance, and it does not mean anything that I randomly showed them :')

Thanks. Should be fixed.
