DragoSim doesn't compute flight costs.
How about implementing such a feature, then? Since the simulator knows the coordinates of the target and the contents of the attacking fleet, all you need, in order to compute the fuel consumption, is the starting coordinates of the attack. Let the user enter it manually and the rest is a matter of rather trivial computation.
Can I help in any way? I do have a background in programming and have implemented the fuel consumption computation in a spreadsheet.
But in theory, it should indeed read in planet coordinates from the espionage report. You can try it by clicking "Read Scan" and pasting the scan yourself.
You know what is the difference between theory and practice? I theory, there isn't any. In practice, however, there is.

When I tried it with Read data/scan, it similarly failed to read the coordinates of the target from the pasted espionage report. I suspect that the problem is that some strings in the report have changed in the re-design of OGame. Here is the (English) report that I pasted:
Resources at MD198 [5:478:5] (Player 'FunnyBear') on 11-11 06:55:54
Metal: 975.883 Crystal: 865.000
Deuterium: 470.000 Energy: 31.584
Activity
Activity
Activity means that the scanned player has been active on that planet or another player had fleet contact with the planet you scanned.
Your espionage does not show abnormalities in the atmosphere of the planet. There appears to have been no activity on the planet within the last hour.

Chance of counter-espionage: 83 %And I should count myself lucky that only the coordinates are missing. The players from the Russian board are complaining that the defenses and the combat techs of the target are missing, too. Again, I'm pretty sure that the problem is caused by some of the text strings having been changed in the re-design.
Can I do anything to help? Perhaps a sample espionage report in Russian with all parts (resources, ships, defenses, researches) visible and the contents of the technology tree?
