When I use 1.21.1, neoforge21.1.146, there is no error on the server side, but the client prompts that spectrelib is needed to connect to the server, so I went to the mvnrepository.com and downloaded Spectrelib common 0.17.2 1.21, and when I imported it into the mods folder, neoforge told me that it is not a valid mod file. So could you do it without using this lib and achieve the 1.21.2 official pause function?
