Ship floats away into the air and loot is lost.

2 friends and I were less than a minute from the outpost with our fortress loot. The Kraken shows up, we were super scared and excited since it was the first time. We were fighting it when suddenly we were free of it and then our ship started floating into the sky, I also recall seeing a ship flying away in the beta. Shortly after our game crashes and all is lost. Not sure if this bug was related to the Kraken or server issues. Just wanted to address it.
