Describe the bug
Placing two or more sections of custom curve track such that they overlap will cause a NullPointerException to be thrown.

How to reproduce
Steps to reproduce the unwanted behavior:

1. Get Custom curve track (rail bed and fill doesn't seem to make a difference)
2. Place track section 1 and build blueprint
3. Place track section 2 so it overlaps at least once with track section 1 and build blueprint

If it doesn't place at all, try placing the ends of section 2 in reverse order.

Expected behavior
Tracks are placed and appear correctly.

Actual behavior
NPE is logged (VanillaFix), rail bed is missing in sections, rail blueprint block is not selectable in sections.
