"Refund All" on the skills page froze the game. Skills only have 1/1.
The exploration happens very slow when you are in the odyssey tab. Switching tabs makes it go much faster.
Can't manually explore Colossal Eel in the Wooded Islands in Peninsula. Also can't explore Jungle Hydra after unlocking the route from River Pass.
Refreshing the page resest Essence multiplier. In Essence tab, "Unlock Energy" has 10 levels, "Boost Energy" has 1 level.
Looks like there are achievements and tournament fights offscreen but can't scroll to them, although I did somehow tab down in the achievements page once.
