If you copy a message from the chat log (using the new copy button, not ctrl+c), and then paste it to the chat box, it will be pasted twice. "CopiedMessage" will be pasted into: CopiedMessageCopiedMessage.
When using ctrl+c to copy YOUR OWN will, the same issue occurs. Your will is copied twice, and pasting it to the chat will post it twice. "SheriffN1-4Inno" becomes: SheriffN1-4InnoSheriffN1-4Inno.
This issue began today, never happened before. I have no screenshot because I don't think this issue requires a screenshot? I wouldn't know how to screenshot something like this anyway.
UPDATE: Now it seems to copy 4 copies of whatever I copy. I had this in my will: "START BY LYNCHING 8". I copied it, pasted it right below itself a single ONE time and got exactly this:
START BY LYNCHING 8
START BY LYNCHING 8
START BY LYNCHING 8
START BY LYNCHING 8
START BY LYNCHING 8
