I'm not sure if this is the correct place to post.
Yesterday night I've installed an empty navdata.db3 in the 5.00.047 software.
It started to populate nicely, and there is no more high CPU usage while navigating my log.
But this morning I've noticed that some aircrafts do not populate:
4D0103 - LX-VCA
896218 - A6-EGW
4A0689 - YR-ATI
45C262 - OY-PSB
780175 - B-HXH
7C492B - VH-OQL
I've extracted the above regs from a backup database from 2013/08/19.
All of them have more than 30 entries in mylog since the beginning of July when I emptied it.
