Server crashes when trying to plan some probably really weird road

[msdsk]

Platform: macOS 10.12.6

What I was trying to do: Create a loopy road that would cross an old one in two points:

After that I wanted to create another one, right where the first one started, but when I clicked only circles appeared without actual roads appearing. I double-clicked to finish the (non-visible or non-existent) road and the server crashed.

What happened: Server crashed with a following information:

SIMULATION BROKE :(

WHAT HAPPENED:
index out of bounds: the len is 10 but the index is 10

WHERE IT HAPPENED:
at game_common/src/planning/interaction/mod.rs, line 271
