If all Duplicants are dead or deleted (realistically only happens in Sandbox mode colonies), opening the Exo-Suit Forge will crash the game.
Steps to Reproduce
- Start a new Sandbox game
- Research the Atmo Suit (normally or with Debug)
- Build and power an Exo-Suit Forge, but do not select it
- Remove all Duplicants with the Destroy tool
- Select the Exo-Suit Forge
- Game will crash
