Hi, I just noticed, that this bug is back in latest git trunk.
I already filed a bug report and it got resolved, but it seems viking is now again deleting tiles if auto download map is enabled and there is no connection to the internet. Can one of the superusers please reopen this bug http://sourceforge.net/tracker/?func=detail&aid=3042692&group_id=83870&atid=570954 Thanks BTW: At the moment navit saved my live cause it can render osm maps on the fly offline, but it lacks gpx way- trackpoin layer support. But who know, perhaps viking 2.0 will be able to render osm map tiles on demand.
