Help!!
I have just started to use fleet experience and it is not uncommon for me to transfer ships to and from a fleet with 20 or above fleet experience.
Also, it is not uncommon for me to empty the fleet with 20 experience.

<==at myself.
I got into the bad habit of just exchanging ships and if I deleted a fleet, so what, just create a new one!
But now I want to preserve the fleet with 20 or above fleet experience.
As much as I try to leave at least one ship in the experienced fleet, about once in two turns, I still destroy the fleet by emptying it.
Is there a way of resurrecting the emptied fleet that I do not know about? Or of locking it, so it will not empty?
If not, do you guys have any tips that you use which help prevent you from emptying your fleets.
