I too have suffered this out of gas problem from liqui and been waiting for more than 5 days now for the ETH to be restored back to my account.I believe we need to wait for a few days and if we don't receive a response need to start a scam report against liqui, so many people stop using their exchange.
Yeah, I hope they're just very slow. I've seen people asking for Ukrainian lawyers etc, they really need to pull their act together and show they're not scammers before someone takes action. Out of curiosity, did you happen to withdraw to Bittrex/other exchange?
Bittrex and some to my wallet.
