I decided that I might as well help out a little and I did find something interesting.
This line (#133 in my save) here:
The number right before the @ is the AI home world defense budget if you are playing Fallen Spire. Knowing that, I am assuming that the numbers after the 29, part is the Current buildup for the next Exowave and the target for the next Exowave.
Now all I need to do is track down what ships are my ally spire fleet so I can remove several 10s of thousands of them to stop the heap crashes and I might be able to get that win on 10/10, rather then cry at the fact that the game keep crashing due to heap issues with the fleet right outside the last homeworld.
Confirmed that the 238000 line is the current charge. Setting it 0 removes the incoming EXO-wave warning.
