Hi, was just messing around and noticed this, it’s fairly easy to reproduce.
Firstly, create a character (archtype doesn’t matter) and give them the first voice pack (the scottish accent). You can then start the campaign or whatever and verify it has the correct voice. Then, delete a different character, you will then see that this newly created character has been reset to one of the american voices.
Hardly gamebreaking, but it was annoying me until I found out what it was.
