When I try to use Spigot or Bukkit on my Minecraft 1.13.1 server , the Scoreboard objectives for damage_taken or any other damage_taken variable does not work.
@Juunnas Do not use 1.13 if you are not testing for bugs. 1.13 is extremely experimental, and should only be used to find bugs. Report this issue to spigot directly. Create a ticket on their issue tracker: https://hub.spigotmc.org/jira/secure/Dashboard.jspa
