Pretty much what the title ask: I've came back today after a few days, I've done 10 Campaign and 5 Arena's match so far and I haven't gotten any box. Bad luck or something changed with the last update?
Just completed 1 arena battle and got 1. (only done 1 today)
Nice to hear that then!
I been getting boxes too both in arena and campaign so you just need to put up some horseshoe dream catchers where you play at to grab the bad luck.
