Hello

having conflict with the salt reactor which was removed from Maraxis

Failed to load mods: Error in assignID: technology with name 'maraxsis-salt-reactor' does not exist.

I think you got the wrong mod. Maybe report it to the author of Ribbonia.

it was showing me also lignumis to be disabled, not sure why

Cannot add screen now, but error was showing me that above. Let s see when they update Ribbonia

Lignumis has no code for that. It was listed because it adds the science packs so it's kind of involved but not really.
