Make it so you can have no cooldown, but so the quest can only ever be done once.

Suggestion to add an option to the quests that a player can only do the quest once.

Also make it so can enable the option that players have to complete another quest first before starting a new one.

I've been asking for this for over a year and you and I aren't the first. I'm trying to make a Rust GTA themed server and I can't do linear quest progression. I was hoping the dev's would add some kind of support with the new quest system. It has to be possible, but I'm a bad programmer so can't speak to much on it. I would pay him to add this support if possible.

Ah, well Im working on a roleplay server and could also really use this. https://youtu.be/kOJjlmx3q8w

I Need this aswell thought it was possible. sad to see it isnt, 

Thats a nice idea, now I want it too lol

I wipe my server and quests progress monthly with the forced wipe. If you set the cooldown to 50400 minutes or more, then they will only be able to do it once per wipe
