Since I updated the mod today, I cannot start my Chosen's Modded Adventure because of the attached error.

I note that there is no ParticleMobEffect over at https://github.com/baileyholl/Ars-Nouveau/tree/main/src/main/java/com/hollingsworth/arsnouveau/common/potions but I'm not proficient enough with the javas to work out if yet another mod should be providing this class, sorry.

Thanks for the quick reply! And yes, Prism Launcher wasn't detecting that needed updating, thanks!

You need to use Ars 4.10 minimum, you're on 4.9
