I (Andrew) did a deep dive and found some extra system files that weren't necessary and that were slowing down the game in a few ways. The most noticeable is in battles. The game now won't stutter when using spells/abilities that target a lot of enemies! This has been a huge sore spot since launch and was introduced when we were trying to figure out why achievements weren't working.
A few other small bugs were changed as well as a slight power increase to level III spells.
Let us know how the game runs for you or if you see any issues from this update.
