I have version 2.4 downloaded from this website (I downloaded it maybe a week ago).
I have Windows 7, 64-bit, with Intel HD Graphics 4000.
This bug has happened twice, each time with a coastal mansion battle - once in central America, once on the southern coast of the US. The exact description is "A mansion near the coast."
After I click on Enter mission, the game freezes. There is no attempt to load the map.
Console log is attached.
