Why am I doing injections at the start, and again at the end?
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.
Oh well, at least it's fixed now.
