from a reddit comment:

Allegedly, it seems to have three prerequisites:

the death must occur in daytime shelling: at least one enemy must survive, at least one of your ships must not be taiha. In other words, you must get to the choice between Yasen/Withdraw -- and then click on neither but instead just close the game. If you then wait until the map is removed, such as with event maps only active during operations, the results are allegedly never finalized and the fleet just resets to pre-battle values.

In other words, if you neither withdraw nor yasen, the server never actually has a chance to calculate the true outcome of the battle. The fleet is left in limbo until you log in again, at which point I assume the server finally notices there was a battle that still has not been finalized and auto-withdraws for you, locking in any casualties. Except when the map is no longer present, which seems to trigger some sort of failsafe reset.
