It’s also important to note that the landing caused uneven crushing of the landing legs. The result being that the booster has a lean to it and they were unable to fully secure it with the octograbber. The leaning of the booster plus wind and rough seas was required to cause the failure. If the booster was level and fully secured it should have been fine.
The newer boosters have self levelling legs which remove the lean caused by uneven crushing of the landing leg cores.
