Minecraft version: 1.12.2
Wizardry version: 4.1.1
Environment: Server

Issue details: Crash after adding entities to the config for damage immunity. Specifically, I tried adding the Twilight Forest's Snow Queen to the ice immunity list.

Other mods involved: Twilight Forest.

Here are two versions of the config file I was using; both caused crashes: belathus/Wanderlust-Renewed@7828cc7

I'm not the author, but I may want to tell you that this can apply to any modded mobs as far as I'm aware of. (So it can be any mod involved or none) [This actually happens in both environments]

I've only used the immunity list once for the ROTD mod and pretty much getting the same crash like you've described there.

Thanks @Ghostrider231, that tells me it's definitely a problem with wizardry.

Something seems to have gone wrong when looking up entities by name (the entity registry system got changed in 1.12 so that sort of makes sense). I'll look into it, thanks both of you for reporting it.

I've just realised this is because the entities haven't been registered at the point when the config is read. It's an easy fix, I'll get it done for the next patch.

Sweet. Looking forward to it.
