I suspected that much at least and am glad to have confirmation of it. Just 
got and tried what you mean via an answer on another ubuntu forum

sudo rm /etc/udev/rules.d/70-persistent-net.rules
sudo reboot

That seems to have done the job and so I am keeping an eye out to see if the 
behaviour remains re not seeing the interface on certain reboots which would 
now suggest other issues. This has got the interface seen as eth0 again. Now 
I gotta go into firestarter again and tell it to go back to that one LOL

Thx
