I've been playing this mod for a long time, and now that I took the time to make an account here, I wanted to thank you for all the hours I spent with this, and I'm thankful for all the work put into it. I hope it finishes soon, as I'm more than happy to wait, but it's like a kid waiting for a candy shop to open.
With that said, when I played the mod about 6 months ago, I did run into a small problem. It was with Ragnarok. The thorium wiki says there's a second phase involving a bunch of orbs surrounding a primary orb. "Dying Reality: The ragnarok" is what it's called.

For some reason I cannot get this phase to trigger, almost like it doesn't exist period in the game files, since when I kill the three horsemen of ragnarok, I get the crown and the boss fight ends. Just as a precursor, I only used the thorium mod, I didn't combine it with Tremor or Spirit or Calamity.
