Amanda Holiday takes exactly 118 days unsold blue ships (rare). I've been looking since the last time that has brought and that was the last , on November 1... :/ Many guardians we like to collect all kinds of things and that is impossible if you do not bring more often . I think they should raise the probability of Amanda to bring blue ships. Or otherwise not take 3 days to change your inventory again, It would be better each day as it does with its inventory Eva emblems.
