While playing 2.6 I unlocked the Benevolent Trait Outreach II, Explorers, but instead of receiving a class 10 planet I got a dead class 0 world. Also on the same turn the Altarians who have an adjacent star system received a class 10 world. Dont know if we unlocked same time or the bug on my unlock gave it to them.
Additionally the bazzaar is not updated to correctly reflect the ship stats you are buying.
