nice! will have to see if i can get this to work on the 1.20.1 version

well, the cherry picked code with changes loads and the nether side of things works, but am still dealing with the tracks not picking up the custom portals at all. this is in my attempt to get this pr into 1.20.1

edit: turns out that datapack portals is in fact not using the customportalapi jar built into its jar cause i just removed it and the portals themselves still work and light. so it wasnt even running my modified code when i swapped out the jars

edit 2: i think something in the pack is also adding customportalapi

yes, another mod is adding its own copy of CustomPortalApi and i need to track it down. i did manage to successfully cherry pick this PR and get it working on 1.20.1 with the latest Create https://github.com/lexi-the-cute/customportalapi/commit/d8f877ac695df356c5801e3b1c113b91cb70316e
