Me and my friends cant craft the items from de Atum 2, items are the same as vanilla, or the recipe won exist.

Can you try rephrasing your issue? I'm not really sure what you're trying to say.

We are having trouble creating mod items, some are simply not generating anything from the recipe when it is built or replaced with standard game items

Could you please provide a few examples? Preferably just screenshots of the recipe not working.

Hi, I have the same problem, I can't craft the scarab to get into the portal in MP on the modpack Valhelsia 2 v2.2.2a, Minecraft v1.15.2, forge-31.2.0

(Or we don't craft the scarab and I missed smth ?)

Thank you !

Unable to reproduce on a server. I assume it's being changed in the modpack you're playing.
Would you happen to be playing with VetGet, or just happened to have a similar issue?

I guess it's a mistake from Valhelsia 2 ( https://www.curseforge.com/minecraft/modpacks/valhelsia-2 ) , I see the sentence : "New dimensions with The Midnight and Atum 2: Return to the Sands.", but it seems Atum2 doesn't appear in the modlist of the modpack... So, sorry...
Valhelsia 2 problem I guess...
Thank you for the time and work you did there btw !

Ok, thank you :) !!

Looking at the modpack versions, looks like Atum 2 got added 7 hours ago in version 2.2.5a
of the modpack :)
