Me and my friends can't learn the engrams as stated. Trying to learn them does nothing, and they are not in the workbench (which we can learn to craft, along with gems).

The server is up to date, as is our game.

The other mods we use are:
Bridge
Stackable Foundations
Castles, Keeps, and Forts Medieval Architecture
Snappy Saddles & Rafts
Pillars Plus
Big Raft
Stairs Mod with Rounded Walls
Structures Plus (S+)

Learning engrams from other mods has not been a problem, are we missing something on the server?

The owner of the server does not own Abberration, dunno if that would be an issue, since we can spawn the engrams through the console.

Edit: We are playing on Ragnarok
