My friend died on server and his grave appeared. But his grave is Unclickable, he is clicking LMB RMB but he can't take his items back. When I try to take them there is now label such us "you can rob the grave in 1 hour". He can only take it as a block and move from place to place

I believe this is a known bug happening where moving the grave will remove all its data. You can access it through /yigd grave commands. Ket me know if you need any help. My intention is to fix the issue as soon as possible, although at the moment I don't have a lot of spare time

Same here, except it doesnt even show in the graves menu
