Android 4.2 and MTP - PC can't "see" new map files

After upgrading my galaxy nexus to 4.2 (4.2.1 actually) I saw that android 4.2 has now support for multiuser.

I created a new offline map using the Map Create in Orux.

The problem is that when connected to the PC via MTP protocol, and using the PC (Windows 7) file explorer on the phone's memory - I can find only the old offline map files but not the new ones (and yes - I did try "refresh", reconnecting to the phone and even restart the phone).

I guess the problem has to do with the new file structure of android 4.2 and the fact that new files are created in \data\media\0\Oruxmaps and not in \sdcard\Oruxmaps. I guess the same issue will occur with tracks and waypoints as well.

I has to use 2rd party tools like MyPhoneExplorer (I believe WifiExplorer will work as well).

Can someone confirm the behavior?
Is it going to be fixed?
