rollback issue

realm rollback, went mining for an hour, game lagged and all 4 of us who were playing got lagged off and game crashed. minecraft took a while to reload and then when we got on the realm had rolled back! 40 mins! we lost a ton of resources as I was mining at the time. this is extremely frustrating and I would like it fixed ASAP! I have seen multiple similar issues on bug tracker but it says its resolved! it isn't! please fix this as soon as possible.

 

(side note, realms experience major lag when playing. possible bug but this isn't the main point of this report)
