Answering my own question here, if anyone has a similar problem, make sure you don't mess with any outlets BEFORE your awakeFromNib method :P Yeah it's basic stuff but somehow I didn't noticed that a method I was calling in my controller's init was resetting a slider to its default position... moving that call to awakeFromNib appears to have fixed the issue!
