I don't know if anyone have this problem, but when i completing travel log quests (the one's that you need to defeat a certain number of zombies from a specific kind). the quests that i compleated appear again. sometimes they just compleating themselfs and sometimes i have to do them all over again. does anyone alse have this problem or know why this is happening? i'll really appreciate if someone could tell me.<ac_metadata title="travel log problemh"> </ac_metadata>
