Talk:Land Region Investigation/@comment-3403988-20180501212806

West Siberian Plain (interior of Baltic Sea North) requires a higher level (yet unknown) of skill/experience to be able to investigate it. I have done all land areas in the north except this one, being given the message "This land region is not available for investigations yet.  You will be able to initiate investigations as you progress in the event related to the Land Region Investigations."
