This update adds the 'forceLoad' config option, which makes the plugin attempt to load the area around the current location of the touring player even when this is within render distance.
This fixes some issues with NPCs. These weren't getting loaded in, and this option allows you to fix that. You need to regenerate the config (delete config.yml and reload plugin) for the new option to show up. It is disabled by default.
Note: This is a new version of the update I posted earlier, with some fixes implemented.
