I started a Modpack using both Origins and Origins++ and it worked fine when I first started the world, I played for a bit logged out then logged back into the same world a couple hours later and my origin was removed. So I used the item to let me reselect my origin however when I did nothing changed, but it did show the little intro part for the origin but none of its abilities and I wasn't able to use them either

Can you send the entire output log? It'd be helpful in pointing out what may be causing this issue, as it contains the mods you're using, or any warnings/errors that may have been logged by the game
