It's obviously due to you not being on Siege.
Seems like a confused t-map lol. But yeah, just set it aside for 30 days and it will reset to a new location
oh ya I diddid ya try digging along the shoreline just in case?
If you want to unload those 6s, let me know.I've done this numerous times and just throw the maps away because I don't feel like waiting and I have a pile of l6 maps as tall as Big Tex.
