I have statsx activated on my server as well as StatsME (by olo)
THE PROBLEM : At end round, HUD Attackers and Victims does not show up accordingly, or it flashes out immediately. This also happens with KILLER HUD and BEST SCORE HUD.
I already adjusted amx_statsx_duration: 12.0 to higher value also tried to play amx_statsx_freeze, unfortunately did not work.
Also since I have STATSME, I tried disabling avlist.cfg as it may have conflicts with statsx hud statistics. Sadly, same result.
SUMMARY
Need to hold Hud of Attackers & Victims/Killer/Best Score during player's death and or round end until 5 seconds of the next round.
