Hi! I downloaded new mods specifically Minecraft transit railway mod 3.0.1. for versoin 1.17.1. ; Fabric 0.40.1. for version 1.17.1. and modmenu 2.0.14. for version 1.17.1. and they didn't showed up in mod section in the game but they are in mod folder. Is there problem with minecraft launcher version (not updated yet) or that I am using forgeoptifine instead regular forg? Are there any different problems? Mods i downloaded before are working without any problem. Thank's for heping!
