Unaligned checkpoints can break suit idle/return behavior

Misaligned docks may frequently get docks that look like this. When this "No Checkpoint" status is present, the docks are still usable for normal operations but it doesn't seem dupes are capable of using the checkpoint anymore for:

1. Idling. Normally dupes will take their suit off at a dock to idle
2. Refueling. I've had instances where dupes did not return to refuel their jetsuits and I strongly suspect because they couldn't "find" these docks.

It occasionally fixes itself but then breaks on reload. Deconstructing and reconstructing the checkpoint also temporarily fixes it.

(I actually personally strongly dislike the idle behavior of dupes returning their suits. I want them to idle in their suits forever )
