[#678][6.00 Beta 2] Ship formations breaking during IS/OOS transition

[Neloth23]

Version 6.00 Beta 2 vanilla
Note : the saves are marked as modified only because I used the creative start.

I noted an apparent bug causing formations to break when a fleet transitions from low attention to high attention.

To reproduce:

1/ Have your player ship stand out of sight of a fleet and order a L ships fleet to move towards you (see savefile & screenshot "Formation Low Attention").

2/ Check the fleet on the map. As soon as it enters high attention, the fleet breaks apart, some ships drifting far away while other try to retain the initial formation (see savefile & screenshot "formation high attention" for the result).
