Build changes

The tile at the top shows the build that is writing the snapshot on the server right now. If it lags behind the first row of the list, the new campaign file has not been put on the machine yet.

Every campaign change is explained by a comment right next to it: what it was, why it worked wrongly and why the new solution will not repeat the same mistake. What you see here is the short version.

A change is never described as "improved": what it was, which number or rule changed, and what it cost — a released self-check, engine load, a capability given up — are all named.
