Minecraft version names contain dots, but Rust's PathBuf interprets it as an extension which is being changed in theseus/src/launcher/download.rs on line 26 to json. This messes up version names in files as shown in this image:
However when starting the game, the version jar file is added to the classpath as 1.18.2-0.13.3.jar, causing an error on Fabric and a crash on vanilla.
One not too elegant but working solution would be to just use PathBuf#push to append the .json and the .jar extension to the filename.
