Randomhammer crashed in a game! It’s the first crash since May, except for the untraceable crash. Now I know exactly what to do next.

The crash was in an interesting TvP game against cannon-bot Jakub Trancik. It’s a shame not to see how it continued. Randomhammer went with marines and Jakub Trancik decided to build its proxy cannons below the ramp, so Randomhammer (seeing the pylon with its scout) didn’t pull SCVs but waited for combat units. The first marines were not quite able to stop the cannons, and retreated out of sight up the ramp. Terran and protoss have very few strategic reactions (unlike zerg), but there is one when the bot is making infantry and meets dragoons, tanks, lurkers, or static defense: It adds tanks. It was the correct move; the unit control is clumsy and loses stuff unnecessarily, but the tanks were sieging down cannons and I was starting to think that the play was good enough.

Then CRASH! The crash is in CombatCommander::updateReconSquad() which decides what units are in the Recon squad. It is complicated for terran because there may be medics in the squad, depending on size and composition, so it’s no big surprise that there’s a bug.

To work!
