Couple of Qs - retrofitting and minesweeping

[Suicide Junkie]

1) Retrofits do not reduce experience. Capturing a ship via troops or psychics will cause loss of experience.

2) All of the sweeper components in the fleet fire when the fleet enters the sector.
If there are enemy vessels in the sector, your sweepers will be in combat.
The sweepers can break formation and run to a corner while the ships fight.

So sending attack ships and sweepers together means:
- the full sweeper effect occurs
- attack ships enter combat with enemy ships & units.
