Description

After changing the map, the TF2_OnIsHolidayActive forward does not get called anymore. Reloading a plugin that makes use of this forward fixes the issue.

Steps to Reproduce

1. Load the plugin below. The console should get spammed.
2. Change the map.
3. TF2_OnIsHolidayActive does not get called anymore. Reloading the plugin causes the forward to get called again.

#include <sourcemod>
#include <tf2>

public Action TF2_OnIsHolidayActive(TFHoliday holiday, bool &result)
{
  PrintToServer("Called TF2_OnIsHolidayActive");
  return Plugin_Continue;
}
