|No. Of Norns||Effect||Source||Details|
|8+||No creatures can be imported||Hard wired||Even
recently dead norns are counted, as long as they are still in the norn menu
Note that creatures can be injected using third party programd or cobs.
|Hatchery closes||Scripted||Eggs can still hatch in the wild|
|Incubator shuts down||Can be
by-passed by 24 Norn World cob

true but you can get multiple females pregnant when there are 11 or less norns.
This can also be bypassed by the
24 Norn World cob
|Eggs in wild won't hatch||This can't
be bypassed by using Egg Unpauser cob, but can be by No Eggs
Birth instead, which makes them give birth to live young.
