Known issues:

- Saved games may duplicate wall layers (making defenses extra strong)

- Zombies speed up excessively after 5k kills/1k evacuations in saves

- Main menu FPS drops (low priority fix)

- Large install size due to uncompressed tutorial animations

- (Priority) Rescued survivors disappearing in saves – temporarily evacuate before exiting

- Occasionally revived dead units in saves

- Worker/builder count reset to 4-5 in saves

- Builders may get stuck constructing invisible objects

- Builders occasionally trapped between walls (use utility tools to free them)

- Workers may wander (toggle collection tool to redirect)
