Harry and all,

Perhaps related as I'm getting a similar weird result over Tabare [0].

At zoom19, the imagery looks well aligned with an imagery date is 2011
[1] although the image quality is poor.
At zoom20, the imagery is off ~15m north with an imagery date is 2010
[2].  Moreover, there are a lot of changes in the number buildings
constructed.

So I guess zooming beyond 19 (in this area) is not advisable.
