Sometimes the 'Sierra Cloud' was mentioned in Freelancer's text, which is incorrect because Sierra is a field, not a cloud. Given the context, these entries are actually referring to the Tahoe Ice Cloud.
The asteroid field next to Perth station in Edinburgh is called 'Tain', while in the respective .ini file, the field is referred to as 'Skye'. Furthermore, some bar rumors also mention 'Skye' rather than 'Tain'. Because I assumed the rumors and ini references are correct, the field has been renamed to 'Skye'.
