Account Sync

This might have been covered under bugs but is there any way to prevent my angry birds epic account from “syncing”. It seems to happen whenever I am 4 levels into a daily dungeon or about to deal a final blow to a boss. I immediately get kicked out of battle, lose my FB connection and can’t reuse a friends bird (on the daily). This is pretty screwed up in general without even mentioning out rediculous it is that the game doesn’t save dungeon progress.

So yea, how do I stop the sync.
