The following features are added to bunker silos by this script:
1. After opening, the silo may be closed once again to prevent moisture buildup during rainy seasons. The problem that stops the open silo from opening further may also be fixed with this.
2. The silo may be reopened to allow for further filling if the fermentation process is not complete. The fermentation process is therefore lost.
3. It is possible to empty the silo entirely.
4. Various silo tarps may be used to cover the silo.
