If you're looking to use the frame under normal conditions (ie light road use) and it steers OK, then consider it a 'cosmetic problem' as it will have shortened the wheelbase by a few mm. If you'e after making a mint bike, or doing it up to make a mint, its a no-hoper. The cost to repair it will signficantly outweigh its resale value. sorry!
