Error/ bug for snowballs

Hello everyone,
i’m currently facing a little problem. I’m trying to collect every snowballs but some of them are missing. I’ve checked their locations on the wiki but i don’t have them all. They should be 40 snowballs in Settlement Juliet but I have in total like 36 with the other city/locations.

Did you got the same bug ?

Update : i did all the locations (Torren and Holon) but i still have 54 snowballs.
