I've already discussed on this before, however I've noticed I can use mcfunction files fine in the Overworld, and by running them manually, however if I go to run them in a different dimension, running functions manually still works, however any schedule at all refuses to run at all. I know this works because it did in 1.14.4 which is the version I previously used, however schedules do not run in The Nether nor The End. I'm not sure why this is, I've even used "execute in minecraft:the_nether run schedule...." and it still won't run.

The path is fine, the code is fine, I can't seem to find what the problem is. I've tried researching through changelogs and I'm struggling to find anything between 1.14.4 and 1.16.1 talking about schedules in dimensions having changes. I'm hoping this is a bug because this datapack is very important for my server.

If you need anymore information, let me know what would help you understand further.
