A little surprising considering there was a helium valve leak they detected like a month ago that caused a scrub, but decided it wasn't worth taking it apart to fix, just send it and it will probably be fine.
They investigated it and found out that the thrusters wouldn't stop working unless there were 3 more leaks of that size, or a single leak of 100x that size.
The affected thruster system is the backup for the backup for the system they actually use to maneuver.
