Lost all network maps after restart

Dear All,

I created our company’s full network topology with dude.(it was 3 days :frowning: ) After mikrotik hex restart i lost all my maps. What can i do? It looks something is in the disk2/dude.db file. How can i get back all of my lost maps? Please Help!
Thanks in advance!

Ok i find the solution but the cause not:
I had to change the data-directory to
/dude set data-directory=disk2
or
/dude set data-directory=disk1
But i don’t understand why is it changing after shutdown or restart.
