Larian Studios Forums Divine Divinity (English) Technical Problems Solution for patch and disappearing maps

This is the fog-of-war, single blocks? Did you re-load a save from v1.32 or before? If you start a new game, do you still get this problem?

Try deleting all of the files in the '..\Divine Divinity\Run\Dynamic' folder.
This folder is used as a cache for the game. Files are created / copied there from the save game folder when you load, and written / copied from that folder when you save a game. The files will be re-created as required the next time you start Divinity. If there was a corrupt file in that folder, deleting the files should fix the problem.
