i'm new to modding so please bare with me. I'm currently trying to update someone else's mod for my own personal use, IntelliJ only came up with one error which i believe i have fixed as there are no more errors showing, and I made sure to up date line 29 and line 97 in build.gradle, but when i give it a test run it minecraft forge 1.16.4 starts up, but the mod doesn't show up in the loaded mods button, I feel like there's some simple step i must be missing, but i don't know what it could be or where to look.
I have spent the last two hours searching for any information on the process to updating mods incase i'm missing a step, and haven't had much success, if anyone can send me a link to a page on the main general steps or process to updating mods, so I can read up on this and learn, or if you know what the issue is, i'd appreciate the insight. thankyou for your time.
