Predictions occasionally very inaccurate

[Steppschuh]

May be caused by empty / null locations or a rendering bug. Anyway, it shouldn't happen.

Probably caused by missing latitude or longitude in predicted locations. Rendering bug happens in BeaconMap:

    protected PointF getPointFromLocation(Location location) {
        if (location == null || !location.hasLatitudeAndLongitude()) {
            return new PointF(0, 0); // <--------
        }
        float x = canvasProjection.getXFromLocation(location);
        float y = canvasProjection.getYFromLocation(location);
        return new PointF(x, y);
    }
