Setting deathCount to display on both the list and sidebar, I noticed a discrepancy between the two while in a team, as shown in the attached images, the issue also seems to affect playerKillCount, as shown in another attached image.

From what I can make out, it seems that the scores stay with the player, irrelevant of the team, with the sidebar displaying the score with the player's coloured name, while the list displays the player's team score, which does not increase.
