Steps to replicate:
- Place a Rail ramp facing north
- I tested this on Fulgora going into an oil ocean
- Move the camera so that the Rail ramp is mostly off-screen, make sure the camera is also zoomed in enough
- For me, this worked both from map view and character view; at mid-level zoom or closer; and up to about 4 tiles of the length of the ramp could be on screen
- Press Q to pick the ramp; equip it into your cursor; or even just press Shift
- You should see the deep concrete foundations of the ramp flicker and show up in front of the ground
