This is a new version, but this new version is to solve the problem that some people might raise issues at this place. We deliberately changed the file extension of the final released jar file. If you can figure it out and change it, then good luck. Also, in case of model rendering and so on, the author doesn't know when it will be fixed, so updates might be a little slow. It's best to repeatedly urge them in the video comment section, maybe twelve to twenty times.
