Last week I was at 40 voodoo masks and have been sailing and hitting the Kraken and streaking to get chests for masks but whenever I open the chest or get the prize from the Kraken it shows I won the masks but it doesn't show it in my silo. Which sucks because I really need them to finish up one of my last two LP's.
If your silo is full or has no open spaces, you will not collect them. I posted the same issue regarding the silo items received when sailing. There should be a warning that you will not collect like a red number as there are when opening chests.
Apologies for the late reply - is this still happening? If so, if you could send a support ticket we can look into it for you.
