Thanx for the fast reply.
3 problems with what you say:
1) There is nothing in the battle report about loot lost. I would have post it otherwise. The amounts just don't match.
2) In the trade tab I see a note about -145 K gas that can be looted without penalty. Nothing about mineral or metal that are missing
3) If I get less resources due to loot limits, that amount should stay with the owner, not just "disappear" :(
