killed hero stays in sector where it has been killed, to recover HP. but in my case it was during siege of my system. so he was staying there and slowly destroy defence of system, even while he was incapable of fight. and my fleet was fighting it over and over, and killing it, and earning big ammount of XP. same situation during siege of AI sector, 0 or 1hp hero is always fighting my fleet and im getting quite a nice amount of xp. 


i think it would be best if such hero restart at home systems.
