**This achievement is MISSABLE**
Playing as any survivor, after the killer has damaged a generator by any means, repair it, until it stops regressing.
This can only be done once per generator
NOTE:
You can also progress the achievement if the killer has perks such as Surge, that damages the generator, even without the killer actively using the "Damage Generator" interaction.
Certain perks, such as Rookie Spirit by Leon Kennedy can help you located damaged generators.
This can be done on any map.
