there were several points where I missed something.
1. I shouldn't have gone digging first. I did that theorycrafting when I was debating about swarmlings, but when I decided on the nomads, I forgot that they have the sandstorm.
2. I should have nabbed that tile you bridged to earlier. I had you surrounded good.
3. I miscalculated the number of points I had for towns (counting religious buildings for 1 more than they are worth)
