I'm making a modpack for a Fabric private server, and although there is a 1.14.4 version option in Technic now, it still downloads the 1.14.3 jar. Otherwise, everything is fine. (I can manually overwrite the jar and things work then.) I tested this with some other packs, including the official vanilla 1.14.4 pack, and that also runs the 1.14.3 client. Is this a client-side error?
