When creating a world, or joining an existing one, with both mods active, the game crashes to desktop.

I was able to consistently recreate the issue using only Rubidium(0.5.2a), Rubidium Extras(v1.3.1), Rubidium Dynamic Lights(v1.3.1), and Ars Noveau(2.4.0)+dependencies.

I also tried turning the 'dynamic lights' setting on and off for both mods, but the crash still occurred.

I have also posted this issue on the Rubidium Dynamic Lights page, as someone experienced a similar crash involving the ATM 7 mod pack.

I'm experiencing the same issue on one of my custom packs with dynamiclightsreforged(v1.3.1) + rubidium_extras(v1.3.1). The crashes stop occurring whenever I disable Ars_Noveau(v2.4.1) + dependencies.

Here is my crash log if it helps at all:

This is a change they will need to make, or PR for. In the meantime, this version and 1.19 now support full dynamic lights when using /ars-light on. It is an identical implementation to that mod. You can add new sources via the client config.
