Ran into a couple problems in the downloaded version
1. there is a database bug when disbanding fleets. the ships still exist in the registry, but can no longer be accessed and still cost resources.
2. the precursor corvettes event gave me something like 60 corvettes! 10 fleets of 6 each. a major blow to my economy, especially with point 1 above.
now one thing truly annoying and i think silly...
why can you no longer blast enemies into smoldering ruin? I HATE invasions!
