Known issues/bugs:

- Walls/defenses become multi-layered after loading a saved game (makes walls extremely strong)

- Zombies/infected become very fast after 5000 kills or 1000 evacuated when continuing a saved game

- Low FPS in main menu (under investigation, lower priority—apologies)

- Large install size due to how-to-play animations (uses uncompressed GIF frames for clarity and smoothness)

- (Priority) Rescued survivors in holding disappear when continuing a saved game—fix coming. Workaround: evacuate via chopper before quitting

- Occasionally, dead units appear alive after loading a saved game

- Worker and builder counts sometimes reset to 4/5 when continuing a saved game

- Builders may get stuck building something invisible (can still execute latest build/unbuild commands)

- Builders sometimes get stuck between walls—use the finger tool in utilities to interact

- Workers may wander off—toggle collection tool to return them to work
