[15.1] Doodads not removed when placing curved rail

[Redominus]

The game doen's delete small plants when placing curved rails(manual or bot). Plants get cleared when placing rects and diagonal rails.

Thanks for the report

This is due to the collision boxes of the curved rails being, not ideal,
As such this issue has no easy or simple solution at this time,
So i will move this to known issues
