This patch fixes a nasty issue with coins not updating properly when you reloaded a map. The fix is retroactive so your coins will be restored to what they should be based on your progress and upgrades purchased. I'm extremely sorry this wasn't caught sooner.
I've taken the opportunity to also trim the ability costs, so you can get the higher level ones a bit sooner.
There was also a potion shelf hiding in the Leviathan Store, which was difficult to find. It's been placed in a much better position now. Your save file is not affected.
