Patch 1.03 has been released by Bohemia, a solid patch fixing many of the issues known to those of us who play it. The patch does not affect your previous campaign saves, although some edited missions must be unpacked, opened and resaved. This is necessary only if you receive a static object error.

Version Highlights:
* Major AI tweaking and balancing (especially AI infantry can hear much less)
* Improved multiplayer and cooperative campaign (saving games, connection issues)
* Numerous fixes and improvements in the Harvest Red campaign

Good hunting.
