I'm trying to add this to my Pyanodons-modpack new game.

Error loading mod: core/lualib/dataloader.lua:18: Invalid prototype array {}
stack traceback:
[C]: in function 'error'
core/lualib/dataloader.lua:18: in function 'extend'
ManyMoreSciencePacks/prototypes/recipe/recipe.lua:118: in main chunk
[C]: in function 'require'
ManyMoreSciencePacks/data.lua:10: in main chunk

It was an issue with the alt recipe setting being turned on when no mods add alt recipes. It's fixed now.

Pyanodons-modpack mods are now optional dependencies. MMSP packs are needed for pyanodon techs. Not balanced but functional.

Thanks very much, the game loads fine now.

I have a new issue tho, my new game/map never finishes loading. Could be a conflict with another mod or something, I guess.

Just in case, this is the screen I'm talking about:

It just loops indefinitely

Could you send me your full mod list?

Sure, here's my "mod-list.json" and "mod-settings.dat" files from the mods folder:

I hope that helps
