I've spent a really long time on this and It's just not working. I know this might be easier on discord but I don't like discord and I'm unwilling and unable to use it. I'm doing everything in the YouTube tutorial right as far as I can tell but I can't seem to get an origin to show up on the selection screen. The game itself is running fine, I've only had a couple crashes when I messed with the files a bit much, but I can never get a basic origin to show up. The example origins worked fine, (I was using the aerum to test stuff if that helps.) But the second I tried to alter anything it stopped working. I can change the description in pack.mcmeta, but that's about as much as I've been able to change without it not showing in the selection screen anymore.
Here's a run through of what I've done, going left to right. Have I made a mistake?

Yes. All files and folders within a datapack (not the datapack folder itself) need to be completely lowercase. That means your Beevian folder should be beevian, and so does your origin file. Don't forget to then update the reference in your origin layer file as well.

For more immediate help with datapacks, I suggest joining the Origins Discord. There are more people there who can help out. :) I only check these issues here from time to time.

Okay so I did that, and it's still not working. Again I cannot use discord, which is why I am here. I'm willing to wait longer if it's alright for me to ask you here. I don't want to bother you by asking questions that should be asked somewhere else though. So if it's alright for me to ask, is there any other mistake I made?
