I was trying to build my base in the end and i had lots of stuff on and this happened twice. I was building out. no claims or anything i was minding my own business when the block lagged out and i fell. I lost so much op things you can hardly get. Everything i worked for all gone. Until its fixed i'm not playing op factions unless my friends needs help <3.
It was probably a lag spike on the server, it happens sometimes. Putting your stuff in claimed chests would of prevented you from losing most of your stuff when you fell. There's nothing else we can really do. Archiving.
