I found the .biq files finally later last night, however, I find no evidence of a Liberty Ship wonder. Also, I scaled your map out last night, and your north-south scale is about 40 miles to the diamond, and your east-west scale is about 70 miles to the diamond. I plugged in an average for the miles of 55 miles per diamond, with this giving a range for the B-29 of about 32, with corresponding increases in other aircraft ranges. I will send you some more information this evening on other aircraft and ships. Also, a division should be 4 times stronger than a regiment, not 2, because of the additional support troops present with a division.
