Offline map rendering near borders is rather distorted: Some streets are not connected properly. This is best demonstrated by screenshots:

This is roughly https://www.openstreetmap.org/#map=17/49.20217/6.96757. You can see that the yellow main street is not connected properly.

This is roughly https://www.openstreetmap.org/#map=17/49.20421/6.94788. The "Rue Pasteur" roundabout-like structure being teared apart is the most noticeable bug, plus all those side streets of "Rue de Verdun" not being connected to the latter.

The affected map tiles here should be "Germany - Saarland" from 2016-03-04 and "France - Lorraine" from 2016-03-04 (not sure about the name of the latter in English; this is the French name, German name is "Lothringen".)
This is using OsmAnd~ 2.1.1 from F-Droid on CyanogenMod 12.1.

Problem appears only at 1-19 (sometimes at 1-20) zooms when France - Lorraine and Germany - Saarland maps are installed together. But when France - Lorraine is the only map these roads are visible normally.

I am actually surprised to see these streets in the Saarland map, they are all entirely in France -- the boarder is a few hundred meters to the East.

Maps are overlapped to avoid gaps.
