Hey, great to see these over in 25! You'll probably get this from the other comments but the collision filter mask for the fill nodes is different in 25 than 22 so it's not triggering at fill stations. For anyone else looking and wanting to fix themselves in the editor in the mean time this is where you can find it

It's the giants editor available from giants software GDN. The i3d files of the carriages can be edited and the exactFillRootNode you can see with the arrow I drew on the left needs to have the rigid body collision filter group / mask changed in the menu on the right, in the new editor you can just click on the preset and find the exact fill node there and it will pre-fill the hex for you. (if image is hard to see right click and open in new tab)
Thanks for responding to me. This is my first time doing anything like this, and it's definitely more particular than I thought it would be. The I3D files have the proper inputs now, just trying to get the game to notice the edited and rezipped mod file now. Don't think I changed anything but the fillRootNode, but I have the original working file, so evetually ill make it match up properly and work
