Derek, is this:
Fixed a crash that could happen between turns
the bug where you click End Turn and there is a "soft crash" where you can move around, zoom in / out but you're stuck because you can't go to next turn anymore? I reported this in 1.20 here:
After me several other people reported it in 1.29. I've been playing 1.30 and 1.31 for the past few days and it is still happening. I am guessing it's a threading issue. Having to quit the game and reload over and over kills the enjoyment of the game. What can we do to fix to persistent bug? Do you need save games?
