Hello,
I would love to clarify!
So, it mostly depends on how long you've been gone. If you have been gone for more than 3 months then yes, your residence was unclaimed and unprotected, which led to the theft/grief (which still isn't allowed nor supposed to happen). Or, if you have been gone even longer then that there was a while ago (months now, maybe a year?) that the server was reset when updating, but it wasn't for the recent 1.16 update. I would love to help you, please let me know when you're online. But, coreprotect logs have been reset, so what you are missing may not be able to be rolled back and I apologize for this. Make sure you protect your residence again.
Also, sorry but there are no discord nicknames. Everyone's name's in the discord are their IGN, and that is how it is for everyone.
Thank you,
01Vanna
