I have updated the json file with a dynamic location for the rift loader com.github.Chocohead:Rift:jitpack-SNAPSHOT . It should continue to work across all new builds. At some point there may be a Release version and I will change it then.
If there are any problems please report on the YouTube video page https://youtu.be/y_4BlbBXEHI . I do not get notifications here.
