I tried to make this craft 3 times, but I constantly got just a ghost block, what am I doing wrong?

For some reason the 5x5 field is bugged in that release, build it in a 7x7.

What version and are you on a server?

1.2.1

Server

nothing works anyway, ghost block again... :((

I don't have the patience to play this modpack anymore, there are only bugs everywhere, I already spent a lot of resources to make this runic matrix, and I didn't get anything

ok thanks you

In case you didn't know, you're playing on a very much outdated version of the pack. That bug and probably every other bug you've run into is fixed already

I'm not the creator of the sevrer, even if I ask the creator to update the modpack to a new version, he won't do it :(

Ah, that's unfortunate.
