I was in a SNG, chip leader by quite a big margin and 4 people left. Got DC'd and can't get back on. Very frustrating, but if they award the cash based on chips I'll be satisfied.
This has happened to me on final table in a freeroll before. Full Tilt pays according to the chip stack as a rule if the sng or tourney is voided. I found the money deposited in my account once they were online again. If for some reason it's not there just contact the cashier at fulltilt.
