In QGIS, the projection string for EPSG:3399 is: +proj=tmerc +lat_0=0 +lon_0=15 +k=1 +x_0=5500000 +y_0=0 +ellps=bessel +units=m +no_defs This projection string has no datum shift +towgs84, which I would expect for every transformation from the German DHDN/bessel to the WGS ellipsoid. See this page in German for more information on official transformation ...

From Projection Guesser: One of the joys of map making is getting a shapefile without a projection. We eventually decided to stop doing those puzzles manually and wrote ...

Looks like a bug to me, since the projection parameters were not correctly stored or read when reopening (I can't tell which is correct). No errors were raised, and Set / Get / Import methods return a 0 (= good) status, so there are no signals of any errors. You can add this bug to here. If you need a User ID, it is from here. It's also good practice to see ...
