Encountered a serious bug with PVP and PVE kill statistics on weapons (kill trackers): Kills disappear on their own without any apparent reason. Sometimes the stats reappear, but with incorrect numbers (e.g., I got ~200 PVP kills with this weapon, but one day it showed 4000 kills likely pulling from another weapon). After logging back into the game, the counter resets to 0 or another wrong value. I equip a weapon with a kill tracker: Solemn Remembrance or Judgment (Adept) (masterwork weapon with PVP/PVE kills). Get kills in PVP (Crucible) - stats accumulate correctly. Exit activity / log back in / just wait - kills may vanish randomly. At some point, stats may "recover" but with inflated/wrong number (ex: 200 --> 4000, possibly from energy slot weapon). Log back in resets again to 0 or different value. Its not normal.
