If your copilot is clearly donating to the lab but not transferring energy to you, it may be because:

  1. They have not been walking much recently, and therefore haven't generated enough energy to transfer to you. (At least 100 units of energy must be produced to begin energy transfer.)
  2. They are directly donating the energy they obtain from other copilots to the lab.

Please note: the "last online” time displayed in the bridge actually refers to the last time your copilot transferred energy to you.
