ships

Just bought my first new ship and can't find anything about moving modules/weapons. Would really like to avoid the sell/rebuy option because it'd be a waste of money.

On the rescue Ardia mission, after freeing the slaves and clicking Rescue!, game takes me to the ship but fails to proc the text. Game opens the next dialog choice of Recruit/Don't/Exit but there is zero context for it. This seems to be tying into a previous issue I had posted about where...

Can you own multiple ships? I see you can buy but also do a trade in. If so, how would you move ships to tarvos if you buy elsewhere?
