I can confirm this is a connection problem. And you connection to the game server gets interrupted well before the remote scenario you enter. This is why when it`s trying to load your homeland on return to the worldmap - it`s stuck on the loading screen - as there is just nothing to load.
We had a similar issue with another person a while back, but it`s quite rare. Few things you can try:
-If you are on a wireless internet - reboot your wireless router
-Make sure you don`t download or stream anything while playing DoF
-Before you enter remote scenario (quest, view e.t.c), log out to the main menu, and log back in
