2.X-style Curved Rail's placement hitbox extends into the next tile, which causes issues when placing some Buildings (eg, Walls) on the adjacent tile. The hitbox appears to be Rectangular in shape. This is a regression compared to 1.X-style Curved Rails, which have a tighter hitbox.

Steps to reproduce:
- Place a Curved Rail Ghost
- Place a Wall adjacent to the Curved Rail (on the "flat side"), individually or by dragging.
- The Curved Rail ghost disappears!
- Re-place the Curved Rail ghost
- Place a Wall Ghost in the same location
- The Curved Rail ghost stays the same!
- Once the Wall Ghost has been placed, building over the Wall or Rail ghosts does not cause the Ghosts to disappear.

Thanks for the report however we have no plans to change the bounding boxes.

This case was fixed for 2.0.52 - not by changing hitboxes (details in viewtopic.php?p=672631#p672631 )

Sorry, but I am not seeing any difference in behavior in this Test with Version 2.0.55: I am fine with this staying "Not a Bug", but I want to make sure there is no Confusion about what has/not changed here.

Ah. The previous fix was not working on rail-ghosts. This is now fixed for 2.0.65. Thanks for bringing it back up.

Confirmed fixed with 2.0.65 Experimental Release (10 months after original report ).

Thank You! Now I can freely drag my early-game walls, without messing-up my carefully-spaced rail network.
