• Add respawn tickets (2 for testing purposes) via [west, 2] call BIS_fnc_respawnTickets;
• Start session
• Debug console: hint str ([] call BIS_fnc_respawnTickets)
• Hint will return value of -1
• Can also run [missionNamespace] call BIS_fnc_respawnTickets;
• Return value will be -1

Tickets appear to be adding. If you abort, you will see that you still have the 2 that were added via [west, 2] call BIS_fnc_respawnTickets;

If you start session and respawn 2 times (using all tickets) respawns will be disabled and the respawn counter will show --:--:---

Respawn templates fail to end the mission.

Try these:

respawnTemplates[] = {"Counter","Tickets","EndMission"};

or

respawnTemplatesWest[] = {"Counter","Tickets","EndMission"};
