by the way; built in screenshots exist. automatic screenshots exist after you finish your turn. having the option to get an automated screeshot when the game starts sounds like it would take 1 line of coding.
Technically this is a bug I believe, like polymorphic deadbeats. Automatic snapshots at the beginning were attempted when the feature was released. Unfortunately, it was problematic, and snapshots were incorporated as part of the end fortifications command. A little bit more than one line of coding, as well as lots more server load to check pages that you don't have open.
Why would you want an option? You can turn the snaps off if you absolutely hate it, but why make an option for just one snapshot? That's a bit ridiculous. If this was to be fixed and implemented, then it would definitely need to apply to everyone. I understand trying to incorporate everyone's feelings, but this is pretty clear cut, we don't need compromises like that.
