Hi @Laurentius ,
Until now, the demos I worked on didn’t require a list of running quests, because they used events and comparing states.
Thats why I didn’t think about it at all until now.
Expect is soon! 
Will also check that conditions bug, thank you for reporting them!
Also, remember that is you want a variable in your quest to be saved while running, mark it as “SaveGame” (inside variable properties)
Greetings!
