Wrongful futures liquidations on Kraken

I had the misfortune to have a large position liquidated in September BTC/USD multi-collateral futures on Kraken. The markets (looking also at other relevant term, spot and perpetual markets) were very quiet, and I found out that the reason was a volatile behavior of Kraken’s mark price. The mark price follows the midpoint of the bid/ask spread. At some point the market makers stopped quoting, the bid/ask spread became almost 30% wide and the mark price plunged by more than 10% in two minutes causing my liquidation.

I wonder if people had similar experiences on Kraken. While it is not a pleasant subject to discuss for anyone affected, if enough people come together, we may be able to exert some pressure on Kraken to compensate losses and improve their mark price methodology.
