[0.3][freeze]
I had something similiar except it just froze up upon clicking "continue" button when selecting the housing research. This happens even when reloading the game from a save. I was able to select mining and maybe another later on without picking housing, but if I pick housing then it freezes up.
I had to ctrl/alt/delete to quit game, so don't believe there is a dump file (didn't see one with correct time). You should get the option for the housing upgrade, select then hit continue and that is where it freezes for me, mouse still moves but that is it.

I also have some save files that don't load back up if you want those from this same game. They get stuck on the loading screen.
