The sitrep that gets displayed at the beginning of each turn includes links that take you to the appropriate screen, depending on what the sitrep is referring to. For example, a sitrep report about a revolt taking place will link to the planet in question.
Unfortunately, a bug exists where clicking on a sitrep to a ground combat link will not function properly. It will either crash the game completely, or take one to a blank screen. There is no way to return to the game from that blank screen, requiring one to reload the game to continue.
This patch fixes the link for a ground combat sitrep so that it takes one to the proper planet. There is, however, another facet to the bug - ground combat sitreps are not stored in the savegame. That bug is not fixed by this patch (that bug has been deemed to be minor enough to not require fixing).
