sensor repair bug

[mqstout]

* Get your sensors damaged.
* Repair the sensors to any level except fully repaired.
* Jump into a nebula while someone's repairing them.
* Progress on the repair is lost/reset.

I've tested jumping into a non-nebula and other systems, and the repair progress is kept, not reset, over a jump.

Thanks for the report! I'll get it fixed.
