Have you been to Verdistis before in that game? A similar problem happened to someone with the Dark Forest, due to files being included in the save folder prematurely.

Why cant i save in Dark Forest or go back ?

Check your save folder, and delete the 5 files with an extension of .x1 or .1 (see the above topic).
Each save is a separate subfolder in the '..\Divine Divinity\Run\savegames' folder in the disk version of the game; the download version does not have the 'run' subfolder.
Under Vista/7, depending on how the user accounts are set up, if you install the game to the default Program Files path, Windows can create separate savegame folders for each user, and then map that folder to the game's savegame folder (so it will just see the saves for the relevant user).

C:\Users\ %account name% \AppData\Local\VirtualStore\Program Files\Divine Divinity\Run\savegames


If you have been to Verdistis before in that game, it is possible a file associated with Verdistis became corrupt somehow. In a new save (don't want to make your most recent save worse if this isn't the problem), try deleting the world.x1 file and load the save. The game will replace the world file with the default version, which may eliminate the problem, though quest opened locations would be re-sealed and anything left directly on the ground would disappear (there are workarounds for both of these).

Game crash upon going to Verdistis

Game crashes when I try to return to Verdistis


Hopefully you have the first, and much easier to fix problem...
