'Index was outside the bounds of the array' Crash on Worldgen

[Sos339]

Getting this error when generating a world with spirt and thorium mods enabled.
Terraria custom seems to crash/throw an error when it gets to the thorium generation (around the aquatic depths).
Due to the crash a world file isn't generated.

Using: terria custom 0.5.3.1
Tmodloader 0.10.1.5
Thorium 1.5.0.3
Spirit 1.3.4.1

this issue doesnt happen in standard tmodloader worldgen so its a terracustom issue with the new thorium update

Update:
terracustom 0.5.4
Tmodloader 0.10.1.5
Thorium 1.5.0.4
Spirit 1.3.4.1

Hey @Sos339 - based on the troubleshooting I did with my own issue (#19 ), you might want to try turning down your number of chests to about half of max (i.e. 500-600.) I'm playing with Thorium as well, but I think it might be an issue with any mod that might add chests in places that aren't expected.

I guess I never saw this issue. That error might have something to do with Thorium, I'll try to test this soon.
