This release adds two additional settings to config.yml.

unclaimedCheckDuration: 0d0h1m
unclaimedCheckOnWorldChange: true

The first determines how often the plugin checks all users for any unclaimed listings that might need to be returned. These are listings that are past expired.

The second determines if using the multiworld support, whether to run this check whenever a player changes their world.

The default for the first is 1 minute. This might cause some issues with performance for some, so can increase this value to 30 minutes or so to reduce amount of time plugin is checking.
