Lost logs from guild calendar

Warcraft Logs

Hi,

Logs prior to sep 20 are gone from guild calendar / reports.
I have no idea what happened. I didn’t delete from reports tab.
What would have happened ?

Thanks

What guild and server? This can happen if someone of officer rank or higher decides to take the guild and move it, e.g., renaming it or taking it to a different server. Then the old guild will be re-created and empty.

Yes thanks, someone with higher rank in guild deleted logs.
