Abh mod/Emergency Locker
The Emergency Locker was introduced in 0.5.3RC1.2 (originally 0.5.1). It was originally made to allow repairs on a ship but was considered a cheating part at the time. Its release was belated as the author pondered the issue. It was created to complement the Nanite Damage Control.
When a part which can be repaired is damaged the crew can get a tool kit from the locker to repair the part.
It works like the fire extinguisher and does not need special care. Currently only the warp cores can be repaired.
