SPOILERS || Quest support

[Virida]

For the quest "a knock on the door interrupts your work...", do I need to do anything specific other than raising from capsules a creature of each kind?

Probably late but there are a number of things to keep in mind:

1) You have to be the only owner of the creature you are going to submit, that means you have to get capsules from the cupboard, genome splicer or breed them yourself
2) Only capsules obtained after reaching that point in the quest count
3) All creatures have to be raised to adults and then submitted at the same time, you cannot submit them separately
4) You keep the creatures after submitting their data
5) After submitting all of them you are free to do whatever you wish with the creatures
6) No actual notes have to be submitted, the "data" is collected automatically by the site while you raise the creatures
