If you are using Mr Pibb's 2014 season mod, you may have noticed that the engineer's voice has disappeared.
The Engineer's voice has disappeared as a result of removing David Croft's "welcome to formula one 2013" game opening announcement.
At this time I can not figure out how to only remove David Croft's introduction announcement without affecting the engineer. So you can either have them both, or none at all.
If you want the engineer's voice back, download and install this file.
