While adventuring away from main base, on or nearly the same time each night, the next chunk will not load making progress treacherous as you can still fall in holes or water. Saving and exiting and restarting the game does nothing to alleviate the issue. The only thing is to wait some undetermined amount of time until it may work again. When re loading the realm, the loading screen gets stuck on "building terrain" and will stay there. I have experienced this last an hour, or a whole 24 hours.

Please FIX this issue. There's several people on Reddit /r/Realms talking about this same problem.
