Hope this is basic enough:
1) Was over warehouse to pick up materilas.
2) Entered warehouse.
3) tried to leave warehouse, could not enter ship.
4) Exitted warehouse.
5) Now cannot get to either ship nor warehouse since top left corner of warehouse is "surrounded" by other buildings.
6) Would like to get back into ship.
Message received none, simply no option to get into warehouse I was in nor ship I was in.
Only two ways to go; living fast, or dying slow.
