This issue was only partially fixed from the last version. Earning tokens from exploration rewards pops up the tokens earned notification on the *next* reward you collect (but at least doesn't pop it up for every reward after). Ie. I collected a Kraken and got a Battered Chest. Then I collected a Big Fish and got 2000 Grog + 10 BP and got a 4 tokens earned notification on the Big Fish's reward.
