Having trouble adding this mod to my ATM9 pack. I’m sure I did everything correctly and have never had an issue adding a mod previously.

However it is just not working in game. I have it enabled I can see the .jar in my mod folder. However I cannot find it in game when I click on mods (unless it's called something else). I am also not getting any errors or crashes it just doesn't show up. Anybody have any other ideas on how I can make sure it's added properly? Thanks
