How to block the same quest from starting twice? (similar to treasure maps)

[BlackRabbitMsk]

Hello everyone.

I am creating several quests for my mod and I have encountered a problem: If I have a quest running, the player can run the same quest as many times as they want. As a result, the player can have several identical quests active at the same time.

I tried to create an item and the quest itself (in complete analogy with a treasure map), but then it is still possible to run it several times.

Please tell me how I can prohibit the launch if this task has already been launched.

I would be very grateful for your help
