    Jumping "cans" with steam-spike?
    Buoys that hide under water to ambush ships?
    Mechs that spew fire and enjoy being tossed from air transports?

Zero-K v1.6.5.2 – Fixes

The commander regeneration bug prompted an urgent fix. We also managed to get in an improvement to Missile Silo controls, and address various other issues while we were at it.

  • Missile Silo now launches the oldest missile it has (or the next one it builds, if none are ready) when it receives a Force Fire order.

  • Fixed commanders' autorepair scaling with their buildpower.
  • Fixed some issues with save/load (this included such fun things as crawling bombs exploding in their factory).
  • Fixed Swift speed boost's cooldown bar.
  • Fixed metal spot circle thickness and mex animation speed with high metal mults.
  • Fixed commanders displaying the wrong decloak distance.
