I had something weird happening just now. I was trying to make a post but it kept showing 502 error at first, I kept retrying and after several attempts, it went through but then I saw a duplicate post appear just after the original post and when I tried deleting the next one it wouldn't delete, I edited the post and then tried deleting it but again it didn't delete.

I tried to  remove original one which was at 2:30, duplicate was at 2.42 but after I tried deleting the original it went down and the 2.42 one came before that. Which is something I haven't ever seen happening before.

After several attempts I was able to remove the duplicate one but something is defo wrong.
