I have tried a search but can’t find anything about this issue.
When I change the announcement (using guild admin) the original announcement on guild chat remains and when I return to admin my new text has reverted to the old text.
We are supposed to be able to use up to 255 chars now. My new announcement has less than half that.
Edit : I have discovered that the Ranks titles also default back to the originals when changed.
So also broken
