NPC NamePlate Issue & Reproduction Steps:
When you have mouselook enabled and hover over an NPC that is part of a 'Guild' the nameplate is shown with incorrect spacing between lines and overlaps part of the Level information.

Related Info:
When you just target an NPC (select them as your target) then the bug does not happen and spacing is done correctly. This is very odd.

Workaround:
Temporary workaround for now is to remove 'NPC Guild' from the NamePlate options until this bug can be fixed.

Shortcut Saving Issue:
When trying to clear ALL custom shortcuts for the lower-left corner of the screen, this setting is NOT saved.
Doing /reloadui or clicking 'Save Settings' in ForgeUI or relogging will reset all of those icons to the default configuration.
Everything else is saving fine, no clue what is causing this one minor non-saving issue.

Workaround:
This only happens when you remove ALL the shortcuts and don't replace them with something else. So just choose at least one shortcut to appear at all times and then it saves properly. :)
