Summary

SUMMARY: Bugfixes "Fix Repair Nanobots"

Purpose of change

• Simplify broken limb mending #3054 caused an issue where repair nanobots weren't healing. Closer examination revealed it was due to damaged parts not being updated.

Describe the solution

Add back code that marks limbs for repair, keep mending parts out of it.

Describe alternatives you've considered

Reworking Nanobots for the nth time to do new and weird things.

Testing

Spawned character, damaged torso and one limb to 60 HP. Added self-aware mutation to track HP.
Installed Repair Nanobots, added 100 kJ power.

• Wait one hour, check that no healing and power draw is observed.
• Turn on Repair Nanobots, check that body parts heal and power draw is as expected.

Don't know. I don't typically write tests and thus would have to look it over first.

Edit: Would prefer that this be merged before 0.4 stable goes out though.
