I was going through a friend's Realm when I suddenly started crashing once a specific area was loaded, the game started crashing every time. I checked the crash report, and it's due to an extended piston that is failing to load. As per the crash report "Server forgot to send required information to construct BlockEntity" This was not a problem until 1.10.1 as this was never an issue before. I'm assuming it's 1.10.1 because it's a realm and they always use the latest edition of the game. Right? Here's the crash report.
