I will have to do more research about 1.18 chunk loading. You were unclear about how your code manages with the entity load failure. If you simply used a loop, I suggest submitting a tick task to the next tick which does the same thing, checking if the entities are loaded and if so teleporting the right one else submitting another tick task etc. Also I think forceloading permanently force loads the chunk, and it only starts to unload when you make a subsequent call to mark the chunk as not forceloaded. I may be completely wrong, I dont know much about 1.18, most of my experience is 1.20. Good luck I hope you figure it out after all this time 😅
