I made a datapack the same way I always did 3 years ago and no functions were showing up and the main “tick” function that wasn’t custom also didn’t work. I’ve tried looking at recent datapacks and I cant find what’s going wrong. Like I said I haven’t made a datapack for 3 years and the core file positions and names might have changed.

I tried putting every file in the folders that worked last time I made a datapack expecting it to work, but instead nothing was showing up and nothing was working. Everything is typed out correctly, so it should work.
