Fining a few bugs

Loving the BETA of the new version, however I have found a couple bugs already so hopefully I am not repeating any known reports. First bug is syncing Xbox One worlds to the new version; every time I would sync my world(s), the game would crash and bring me back to the Xbox home. My worlds are around 300-350 MBs each, so I don't know if this version is having a hard time transfering the Xbox worlds or does not have enough data to handle it? The other bug is the Creepers blowing up even when you are at least 7-10 blocks away. It may just be a new feature in the game or something, but I thought it was worth mentioning.
