Errors
- When the trash can next to the vending machines near the Metroline is interacted with, it will state “Trash can with empty drinks cans...”, with an extra “S”.
- When first visiting the dome, there is a sandwich board sign near the vending machines that simply states “Just at the top of the Den Battle Tournament stairs” with no context. A possible explanation is that there was a line before it that failed to load before that the aforementioned one, or that the line was mistranslated.
