creatures taking damage in freeports

[SeaThiever 1]

as far as i know, if you are in freeport, you cant damage any players or any structures on them ships, so why your animals can take damge from other animals? i was with 4 animals yesterday and today when i sgin in i found in my company log they are died becouse elephints, so other players they lead the elephints close to my pets. shops will not take damage if some one will lead animals to it, so why they can lead animals to damage your pets? im really upset, i tame that in weekend any i sail more than 4 regions, this is really bad.
