Bug report!
Got a soldier (Jan Fuglestad) who killed an engineer and navigator and somehow managed to get himself awarded the "Taking names" commendation, which was promptly taken away with a letter blaming an intern who doesn't work at XCom anymore.
I kept some record though, see save attached.
Edit:
The stats tracking side of things seems to work very well, except for being a bit generous with what's a "Night Op". I've got some other issues with the awards though and I am still not well versed enough in this to figure them out (See Com1 save attached):
1 - More "Taking names" were awarded. It seems like killing any 2 ranks awards it?
2 - The Order of Earth is awarded if you fight a medium scout + 2 large scouts. In the logs the missions are properly identified, but the soldiers got the award any ways.
3 - The criterion for night is a bit loose. I often wait until dawn to raid UFOs, so I am not at a disadvantage vision-wise. But that still seems to be considered night for the awards.
Maybe there could be the "Night Stalker" award for when it's dark enough to impair soldiers' vision range, and a "Dawn and Dusk Raider" for raids conducted at low light but full vision?
