When trying to load Minecraft under the Forge client with both Schematica and LuantriusCore [all are 1.12.2, up to date], I get an error in the game. It says that the forge mod is missing, but I loaded it up on the Forge launcher? I might just be dumb but I'm literally confused :(

Edit: this is what it says, visually. http://prntscr.com/hizols

Update Forge. You're using an old version.

What is the "latest" version?

I made sure to download the latest version though.
