Hi, I downloaded SotF R6.4 and play now. It's very fun and I love it!
I noticed about some matters.
for Plague:
BaseArmorPoints and ExperiencePointsForDestroying of leveled light frigate are lower than light frigate.
Weapon damage and ExperiencePointsForDestroying of leveled scout are lower than scout.
Ability of light frigate (and leveled) "Infect AntiMatter" is not unlocked though research is finished.
for Rogue:
Research subjects' names and descriptions unlocking two support cruisers are reversed to really unlocking cruisers.
Research subject's name and description unlocking envoy cruiser is "String Not Found".
for Galaxy:
Descriptions of galaxy "Random Encounters - Medium" and "Random Encounters - Medium/Large" are "String Not Found".
(.galaxy files may have problems.)
