I wonder if the bug I've been getting is the same bug - except mine happens at the end of Turn 1/start of Turn 2 (Starting New Turn message pops up in lower right). Game becomes completely unresponsive, have to use task manager to close it, and then the game fails validation and has to re-download something.
Win 7, AMD FX 8320 8 core slightly OCed, 16 GB RAM, Radeon 7870 graphics card and an SSD. Started game with Insane map, 11 enemies, plenty of minor races and pirates. Just tried it on tiny with otherwise same settings and no issues.
Have you validated files and restarted steam? After trying on "tiny" map did you try the insane map again? Are you running any mods
Same here
Went from insane to excessive. Deleted all xmls & custom races, validated files to replace xmls
Oddly enough I started a game after that with only core races and turn 1to 2 was quick so went back and copied some races with minor edits in the ui (colors/abilities/etc) end turn on turn one gets to starting new turn & that's all
Cpu stays pegged & ram hovers pretty stable. Once let it go for over an hour
Edit: I don't get the fails validation thing
in case of relevance, the tail en d of my debug.err always seems to look like this:

the conversation thing was a first & likely because by chance I bumped into someone (or they me) while I was off making/eating coffee & breakfast
