I was experiencing some lag where I couldn't open some containers and couldn't use a bucket so I relogged, logged back in to find this. There were blocks above the island that were replaced with air. (I rolled back the server)
update: it has occurred again
update 2: this seems to occur whenever I log in on my island, the backup occurred in the overworld so this does not occur when I first log in
update 3: deleted interactionsisland.nbt and am no longer experiencing issues
