This event has been 100% dud for me. Not gonna post a picture cause all of yours will put it too shame, but here's the list:
15 boxes total so far (all from wins):
5 +1 Vet conversions
1 +10 Vet conversion
3 50k Credits
3 50k Points
3 Naval Mines
(Fyi, all of my sailors have 100+ vets on them...)
So, like I said, 100% dud/useless event for me so far :-(.
