Deaths in modes with bots count to profile
If you are playing in a game mode that has bots, your kills do not count to your profile's K/D ratio (including player kills in matches with bots), which is something they said they implemented on purpose. However... dying in bot filled game modes does impact the K/D stat on your profile. Why do deaths count but not kills, either count no stats in those modes, or count player kills and all deaths. This inconsistent in between makes no sense.
Note: I have verified this by checking my K/D before and after dying (as the profile updates instantly) in a Full XP bot fill breakthrough game with 64/64 real players and it went from 1.469 to 1.468, but getting 3 player kills in a row did not move my K/D up at all. So it definitely is counting death stats and not kill stats in those modes.
