The explanation is a little clunky but:

The game usually crashes when it is cycling through my towns and I reach the last idle town before the end of turn. When I click on the next thing to build, if I click on another building to queue up the game often crashes. This has been happening on all the releases so far.

This only happens on the end of turn.  I will click an item to build in the town, the game will start to proceed to the AI turn (little hourglass appears) but the town screen remains open.  If I then click another item to queue during the transition to the next turn, the game often crashes.  It is not every single time, but often enough that I think it is a problem.  Of course I could not click to queue up another build to mitigate this issue, but the game shouldn't be crashing like this IMO.
