Done Base destroyed by end portals?!

Hi,

I just logged in after a short while away...
My base has been taken over by multiple end portal frames? half my base destroyed... all my draws empty of all the resources, most of my chests missing.

...did I miss something?
What's happened?

 

some time ago, there it was possible to place end portals with an item to bypass the claims, which we fixed when we found out. seems that you have been griefed before that happened. i will come on to take a look

 

Closing this as it has been resolved.

 

...so that's it? My game is destroyed?
