Minor issue, but the collision box for the new curved rail is offset to one side too much imo. Looking at the gravel, it seems like the underground belt should be fine there, and the edge on of the collision box below the rail is a lot closer to it than above.
The underground belt on the right is colliding with the curved rail. It would be nice if the collision box of the rail could be moved "down" a bit (relative to its orientation in the image).

Have you considered using flow routers instead of balancers?

Thanks for the report however this is not a bug.
If you want to get ahold of me I'm almost always on Discord.
