According to Fox29x:
The new Carno update with saddle is live but the current download has a corrupt file to fix this unsub from Dino Hoarders then delete the mod folder and resub. Same with servers back up your server. Unsub from the mod, delete the mod files from your server then re-sub and re-download, then restore the backup save. Afterwards everything should be in working order for you to enjoy the new update.
