Known Issues/Bugs:

- Walls/defenses may appear doubled or tripled after loading a saved game (resulting in extremely sturdy defenses, akin to certain political promises)

- Zombies/infected become extremely fast after reaching 5000 kills or 1000 evacuations when continuing a saved game

- Low FPS on the main menu (under investigation but not currently a top priority)

- Large installation size due to uncompressed how-to-play animations (using GIF frames for smooth, clear visuals)

- (High Priority) Rescued survivors in holding may disappear when continuing a saved game; fix coming in the next update. Current workaround: evacuate them via helicopter before exiting the game

- Occasionally, units previously killed may reappear alive when loading a saved game

- Worker and builder counts may reset to 4/5 upon loading a saved game

- Builders sometimes get stuck constructing invisible objects (they can still execute the latest build/unbuild commands)

- Builders may occasionally get trapped between built walls; use the finger tool in the utilities menu to interact with units

- Workers may sometimes wander off; toggle the collection tool to redirect them to work
