Freezing and Crashing

This bug is causing my game to freeze while playing in a realm or server. It didn’t happen at all until I got subscribed to a realm this morning and then it all went to pieces. I’m talking like the game freezes in the middle of exploring a cave which will leave you vulnerable to mobs, because you are technically still there you just can respond. We thought it was a realm problem until we got on a server and it started doing it again. This would happen about every 5 minutes or so. Really frustrating. Btw, our connection for the most part is good. Good enough to play on a server.
