Using "/perms user xxx meta set griefprevention.claim-limit 3" does not give the player the allowance for claims defined in the option. I have spoken with bloodshot to confirm it's working in GP, which means the option in luckperms isn't working properly. Other options that don't include the mod id are working fine however (for different plugins than GP).

@lucko I include the plugin id with my option to avoid interfering with other plugins using the same option name.

@lucko Just tested removing "griefprevention." from my options and everything worked as expected so there is definitely an issue with adding an option that contains a period.

Alrighty, thanks. That's definitely an LP issue.

Options are actually stored as permissions, whereby:
key=value gets translated into the permission meta.key.value

The periods should have been escaped. I'll fix that now.
