[0.12.0] Non-smooth T intersections

[boro]

I'm sure everyone noticed but just for the sake of there being a thread for it:

On a T intersection of belts, items coming from the side lane sort of teleport onto the main belt, instead of the smooth animation we've all grown accustomed to.

Can confirm this one. I think thats the new items on rails - gotten used to it but looks slightly strange.
