Minimal ISO network configuration bug

Minimal iso does not provide manual IP settings, even with Set network manually. BUT that bug only affected if I choose Russian Federation as localtion and language. Tested twice, if I choose English – it allows to set up IP, netmask etc. If I choose Russian Federation – installer just skips that screen and went to mirror select. I switched to tty1 – and it says Debug state 7. With English – Debug state 3. I don’t know – its makes any sense.
