Fitbit nighttime activity

Reevsie123

Now before you think this is about burning calories during the night ......it's not
I have a flex and on the fitbit dashboard the last 2 nights have shown 1 hour high activity just after midnight is anybody else having this sort of issue ?
It does not appear on the activity log just the dashboard, I think it's messing up my figures, I played 5-side football tonight for 1 hour which according to MFP is about 700 calories, fitbit has added on another 400 adjustment, now I give it all when playing but I can't see 1100 calories being burnt off in 1 hour.

Now please don't be telling me the missis is taking advantage of me whilst I am asleep, especially for a whole hour, it does not appear in my sleep report which states I slept soundly all night (with the exception of a quick wee) :embarassed:

Any fitbit users experiencing the same ? Or could perhaps explain my nocturnal activity
