SCENARIO_BLACKLISTS prevents loading a world twice

[ephemeralstoryteller]

Describe the bug

When attempting to load a world using the new SCENARIO_BLACKLIST functionality, from #37575, the game returns an error saying that there is already an existing scenario_blacklist and prevents loading. Quitting the game entirely seems to allow for loading as normal.

Steps To Reproduce

Steps to reproduce the behavior:

1. Use the example mod provided in Allow black/whitelisting scenarios #37575.
2. Load in fine
3. Quit to menu and attempt to load again

Versions and configuration

• OS: Windows 7
• Game Version: 0.D-12155-gb7876ca
• Graphics version: Tiles
• Mods loaded: Dark Skies Above, a mod I'm working on, however testing with the sample mod provided by Allow black/whitelisting scenarios #37575 resulted in the same error.
