Boats randomly capsizing (flipping upside down)

On February 9th we had an issue where our boat capsized while far away from our house and lost the nails because they sunk to the bottom of the ocean and couldn't pick them up. It happened to several boats that we attempted to bring there.

It seemed to happen when we would leave the boat there, take a portal back, and when we returned the boat would be capsized. (perhaps something to do with the way the boat un-loads from the server while we are not there then re-loads when we return?) (but perhaps in only some locations? because that was the first time it had happened)

Keyword searching in the official discord for "capsized" and "boat upside down" revealed that we are not the only ones with the issue.
