Upon going through an electric isosceles in my cargo boat, its inventory and equipment slots completely vanished. I recall this happening in the past, but it hadn't ended the run, so I guess I didn't think to report it. Basically, this can lock you out of important items in an emergency and just acts as a nuisance overall. I believe switching boats or re-boarding from land would fix the problem. This did happen after quite a few hours of play. No isosceles were used prior to that time. Unsure if cargo boat is the only one to be subject to this issue.
Simply using a (cargo) boat, and activating an electric isosceles.
