Many many mods installed so this could very well be a conflict, but I get a crash on startup with the following message in my server log:

Thanks for the info, that's a bug in the mod; should be fixed now. I will release the fix in the next update

Should be fixed in 1.6.1. Can you confirm if it works now?

Confirming that it does indeed load on the server and client, and all recipes (as far as I can tell) are visible in REI. No test done beyond that. The only mentions of this mod in the server log are the initial fabric load and then a few more as follows:

` - vanilla_cubed 1.20.1-1.6.1

[16:44:41] [main/WARN]: Adding vanilla_cubed:magnetic to saved/remote registry.

[16:44:41] [main/WARN]: Adding vanilla_cubed:nourishment to saved/remote registry.

[16:44:41] [main/WARN]: Adding vanilla_cubed:reach to saved/remote registry.
`

that bug should already be fixed in 1.6.2 ;)

Beautiful thank you, I'll install that when I have the opportunity :)

your welcome, have fun!

thats great. If you encounter any other problem let me know

Ok I got one for you :D Crashed while 3 of us were on my server, and I was fighting Pillagers.
