I'm trying to run a minecraft 1.12.2 server on a Dell R610 and have run into issues with the FML not loading the correct mods. The OS is Ubuntu server 20.something.something LTS. The FML always finds 4 mods in the mods folder regardless of whether it is full of mods or is empty. After every failed attempt to get the server to find the mods, I delete the world by deleting the /world folder from the minecraft directory. I have been getting my mods from the curse forge application that I use to run minecraft on my computer. I'm not sure what is wrong with it. I have been following the tutorial in the URL below. I have also attached the info from the server upon startup of the minecraft server. This info from startup is when the /mods/ folder was empty. The file path to the mods folder is as follows: /opt/minecraftforge12/mods . Any guidance would be much appreciated.
