yes, its true; both players must have his savegames. To avoid losing a savegame, i have a folder named "savegames rebellion" with subfolders with the nicknames of my opponets. When i exit from the game but i want to continue another day, i go to where rebellion game is installed, then to "savegames" folder and copy the netgame to the particular folder of my opponent. Then, when i play with my ooponet again, i restore the savegame in his nickname folder to "saveganes" folder where the rebellion is installed. In this way is very very strange to lost a game unless you forget to copy the game.
