+
+        Additional players let you use something like victim as a player to parse in relation to,
+        for example doing %victim_player_health%, which would parse the health of the victim.
+
+        However, something like libreforge will also inject %victim_max_health%, which is unrelated
+        to additional players, and instead holds a constant value. So, eco saw this, smartly thought
+        "ah, it's an additional player, let's parse it", and then tried to parse %max_health% with
+        relation to the victim, which resolved to zero. So, we have to parse statics and player statics
+        that might include a prefix first, then additional players, then player statics with the support
+        of additional players.
+
+        This was a massive headache and took so many reports before I clocked what was going on.
