The new Multiplayer fix mod for Wrath of the Gods (a Calamity mod) highlighted a compatability issue with Thorium. There is a point in WotG's where the depths side ocean freezes and thaws and its at this point yhat Thorium starts throwing errors and crashes the game. It seems that Thorium is claiming some extra ownership over the additional water tiles it creates when it generates the Aquatic Depths biome and this causes an issue when WotG's tries to execute this world event. When you go to update for the new Thorium patch, I was hoping you could take a look at this, too.
