Hi, is there a 1.5 equivalent of this mod?

I tried with no mods and i get an error every time someone tries to give birth , both humans and animals.and the birth fails to generate a pawn

still works for me

Update

I beg of thee a 1.5 update, and my life is yours

1.5???

can we get an option to increase the chances?

plz update o7

1.55555555555555

Please update :)

i think you can get them normally cant you i mean its very rare but it can happen

If this could be made to not affect dogs, that would be great. They had litter births of like 7 normally before this mod :P

Is this meant to target animals?

It won't work because it's not targeting human pregnancy, but animals'

i've tested this mod and i've never had a twin, even went into code to try and increase chance to 90%, and still nothing....
has anyone using this mod had more than one child while its been active?

Does this mod also work with eggs for egg-laying xenotypes like Saurids?

Hey do the chances increase with the fertile gene?

can i add mid pregnancy?

@Kokorocodon 470Kb for me

@peps_win yes you can

Can i add this to a prexisting game

Would love this mod if it was a gene.
Also, it would be great if there would be different quality levels of the gene, increasing the chances.

why is this 9 mb?

If I'm not mistaken this is vanilla since the UI reads 1-3.5 for humans.

speaking of litter sizes, i wonder if its possible to alter the yttakin and Pigpeople to have more kids at once?

HAR has added this feature relatively recently, using the litter size values of humans, do you know if this mod would conflict with what har has? or do they work independently/stacked effect?

Would you like the chances to be equal to real life? Eg 1.2% or like 5 to 10% of the time?

Anything more than 3 has pretty much always been due to IVF

People asking about a ridiculously large number of births realize this, don't you: The larger number of babies, the rarer it is - to the point that it's ridiculously rare - far less than a 1% chance. Heck, even twins are rather rare. Even today, twins are only about 3.2% of births in the U.S. and only about 1.2% worldwide. And, decades ago when medical science was less advanced, it was less: In the 1980's it was only 0.9% worldwide.

Also, the larger the number of births, the greater the risks to both the mother and babies. The human body is not well-suited to birthing large litters, unlike animals such as dogs, cats, rodents and opossums. (Interestingly enough, the reproductive systems of canines and felines are noted by scientists for being unusual - notably different from other animals.)

try nonuplets https://www.bbc.co.uk/news/world-africa-56994408

This would make for a excellent gene option if you wanted to follow a more realistic option, as giving birth to twins or more is a gene that is only becoming more prevalent due to the increased survival rates of such births.

No triplets?

Are triplets possible?

@Indrageerts from some research I believe its a change also made by Humanoid Alien Races. As far as I know and from what I've encountered only single births are possible in vanilla. If that is the case humanoid alien races should really mention it to not confuse people.

is it humanly possible to have octopluts ?

Um... My pawn had twins yesterday.

Yes! I've been wanting my colonists to have multiple births for a while. Will it also work for the egg laying genes of Alpha Genes and Saurids?

Triplets? What about octopluts?
Are they identical twins or do we also get non-identical twins and multiples?
Honestly good mod idea though :)
