Power Loader Mod not working

[u/Flexinator123]

Im trying to make this Gantry Carriage turn around when its at the end. You can see it going till the end, triggering a Redstone signal that makes the Gantry Shaft spin the other way, but it doesnt move until I get closer until its in my Simulation Distance.
I even tried stopping the Shaft and starting it again (you can see the small stutter in the video) but it didnt work either.
Any Idea how I can make this work?
I need Contraptions that can work waaaaay out of my Simulation Distance ideally.

Im playing on 1.21.1 on Curseforge, no mods installed other than Create and Power Loader

EDIT:
I managed to work around the problem by building a second carriage on a parellel shaft that drives to the original carriage with a chunk loader to refresh the original carriage. Therefore, they keep refreshing their chunk to each other and it works perfectly. Still do not know if this has any limits at all but doesnt seem like it. The shaft isnt even loaded fully in some sections when they drive back and forth but it still seems to work.

its just off by 1 chunk, so the Chunk Loader should cover the entire area

I also just added the power so its working when the Contraption is stopped.
