Well, I managed to grab 3 new basic summertime boxes... And my bad luck hit me again
Only got "old" rewards from previous years:
1x Summer Event Suit
2x Galapago Cap Costume
So, nothing new until now. Next time I'll try to open a new pro box and see if Lady Luck will smile for me.
Edit: Got a glimpse of a Toucan pet at Port Malaya. Anyone knows if it's a reward from basic/pro boxes?
