I uploaded Steamhammer 3.5.2 to SCHNAIL today. The version fixes the worst of the problems in the static defense code that was new in the previous version 3.5.1. They were problematic problems; Steamhammer dropped 200 to 300 elo. The change list is short.

• Added a new macro location MacroLocation::Tile for placing buildings at an exact position. Now code that knows how to place buildings can post those buildings to the production queue.

• Taking advantage of that, now the static defense code queues buildings to produce instead of dropping them directly into the building manager, as before. The old static defense code never had a problem doing that, but the new code is more capable and hits failure cases. The production manager that reads the queue already does all the work needed to cover those cases, though.

• Zerg more carefully limits the number of static defense buildings it makes. Sometimes it wanted to put down more than the drone count could support.

Meanwhile, for CoG 2021 my parsing code needs updates to read the detailed results file perfectly. This happens every year. It won’t take long.
