Serious Kraken bug won't let users close their positions

I have entered a short position a few days ago for 20 BTC.Wanting to cut the losses I opted to liquidate the position yesterday, it didn't work and responded with a "Margin allowance exceeded" message.I've notified this to their support more than 24 hours ago, the response I now receive is "maybe try in smaller increments".Liquidating positions (and in more general terms opening a position reducing one's net exposure) shouldn't be checked against any kind of "margin allowance".The net result is that I'm now stuck with this position, that the price moved significantly against it, and that their support is being pretty dismissive about this issue that could possible impact anyone who attempts to margin trade on Kraken. via /r/Bitcoin http://bit.ly/2i8B4Hq
