What gameplay feature is this bug affecting?
Blocking

What's the issue? Please include any error messages you receive and as much detail as possible.
I had blocked a user through chat, and believing they had been blocked, i continued.

They appeared again and i thought it was their side, so i blocked through chat again.

When i went to my 'blocked' tab to edit the reason to remind myself, i noticed it was the same account twice

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
N/A

Any screenshots you can provide us with?
I dont think this /needs/ a screenshot because its just the same person twice in my blocked list, but if it does i'll update

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
I used the block function in chat through the three dots.

Edited the reason for the block in the blocked tab

Person showed up again, so i used the function again the same way.

Went to blocked tab, saw the bug.
