Link to crash log: https://gist.github.com/neoc666/e00d58163ec1653d0cbd862d9a1cdd8f

Steps to reproduce:

1. Navigate to Baubles section and open entry "Planetstrider's Sash"
2. Click page forward button -> immediate crash

Does this happen with only Botania installed?

I fixed this already

When we ask for version, we are referring to Botania version. Not your modpack.

Unable to replicate with only Botania 350

It doesn't seem that you're involved with developing this mod.
