Just had this response from CS:
Thank you for contacting us! This is Game Master Rayn of DomiNations Support Team. Upon investigating your concern, we have verified that your current chance of finding fur of 40% already has the bonus of 20% from your Hounds research. With that said, the base chance of finding Fur from a Bear upon reaching the Cold War Age is 20%, which is unique to Cold War Age and compared to other animals.
We hope this has been clarified for you, and should you have any further concerns, please don't hesitate to contact us again.
Best Regards,
Best Regards, that's hilarious! Welcome to the CW age!
