Hello, you may want to take a look at the ESRI images in the ID Editor; they were only recently taken in the first quarter of this year. These have good orthogonality (90 degrees from above). I used them when (re)mapping Burrel (https://www.openstreetmap.org/# map=16/41.60912/20.01005 ) and personally believe that the footprint of the MS building does not accurately reflect the outline of the building in terms of either size or exact position (image offset).
By the way, your 100-day mapathon motivated me to map in Albania :-) BR
