On Metallurgy or Rubber, must you replenish the face-up tech cards before you invent?
A publisher staff member quoted the Reference Guide's wording on BGG.

No. The Reference Guide says you may discard all three face-up tech cards and replace them, then invent one tech card (two with Rubber). Replenishing is a choice, not a requirement.
