restricted undo

[WhiteRabbit1981]

First: I love the undo feature, it makes a LOT of things that much easier.

In a game today, i accidentally typed "/undo 32" instead of "/undo 2". Funny, it worked like a charm. But i hereby request a message box asking something like "do you really want to undo more than two entire turns?" :-)

To restart a game in the same kingdom, i can just "/undo 200" before buying the last province. Would it be much work to have a "replay kingdom" button instead?
