Error: Loading VFS index
This error occurs sometimes after an upgrade because the previously installed VFS core didn't get transferred over to the new install correctly.
To resolve this,
Stop Voyager.
Navigate to the Index V2 folder located under Voyager Install >> Data >> IndexV2.
Remove the VFS folder located under the IndexV2 folder.
Restart Voyager.
NOTE: This prompts Voyager to create a new VFS core from scratch. Deleting the previous VFS folder shouldn't delete items from your index.
