Going to step into this cluster...
The following pictures show 'The Idiots' claims, of which were placed prior to 'Lost Krakens' claims. The first two pictures show the North side of 'The Idiots' claims, these claims were put down weeks before the Krakens ever showed up. We built this wall because somehow they dropped a claim that was halfway across our original claim as shown in picture three, this picture is the other side of photo one and two. We had plans to build on the beach of photo three to have another shipyard for new members to one of our alliances.
In photo four and five the Krakens again had somehow placed a claim directly next our previously claimed land. Again in the interest of keeping our previously claimed land that one of our members had planned on building, we walled it off as to not be screwed over of our claims that were dropped PRIOR to the Lost Krakens.
*Edit* This is a "bug report", which somehow Lost Krakens were somehow able to place claims halfway into ours that were placed prior and are still there. Not a place to argue, if you'd like to argue please add me on steam or speak to me in game.
