If at the time certain variables are used and empty have the ability to add fallbacks.
For example if {{player,kills}} in some games is used before the player has any kills it shows the variable instead of just 0.
So the easy solution is fallbacks.
TicketTool.xyz bot does this so I will use their idea as a suggestion.
{{player.kills?fb=0}} would create a fallback of 0 if the variable is empty at the time it’s displayed.
?fb= could be added to every variable too to ensure the variables never show publicly.
