Custom game - Strong Immune setting working as intended?

[NuriaSabr]

I'm playing with a custom game using the strong immune system setting.  I have made a strong effort to keep down germs, and can happily say that I rarely have germs on anything.  All my Dups have germs IN them though.  I haven't figure out why they always seem to have food poisoning germs in them, but they do.

I broke out 5 blocks that had slim-lung germs (ceiling the area with a wall).  As soon as I broke into the area that had slim-lung my Dups got Slim-lung germs IN them.  Immediately at exposure, they each had 10,000-15,000 germs listed on their details tab.  Since then they've had no more contact with Slim-Lung.  

 

It's been about 15 cycles since them, all my Dups are now Slim-lung free.  Not ONCE did any of their immunity ratings go down.  It stayed at 100% for all of them the entire time.  The details tab listed them as having a -8% immunity score most of the time.  I was expecting it to go down.  I don't know what the Strong Immune setting is suppose to give, so I'm not sure if this is expected behavior or not.  If it is, yay.

Each disease causes the dupe to lose some "immunity points", but dupes generate 10%-20% of those (10% at weak, 20% at strong immunity setting) without any immunity skill. At strong setting, you need at least -21% from the disease to see immunity go down. Or -6% but also hypothermia or heat stroke.

Your food is probably infected. The only way dupes can get food poisoning inside them is while eating. They can get it if they pick up food and eat it while they're germy themselves, but they can also get it if they're clean but the food has germs on it.

Yeah the colony is not meant to be germ free. Just keeping them from growing wildly out of control.

Try to break open a polluted oxygen pocket with slime lung and let it flood your base. Then you will probably see some immunity go down after a while.

Or just stop cleaning their hands. Once the first dupe starts puking it is critical or everyone will get sick.

All in all the germ play is great and the disease we have now is easy to contain. In the future I see much more hazardous germs and radiation.

Thank you for the input.  I'm really enjoying the new system so far.

The Impervious Immune System Setting isnt that carefree as i hoped.
They still get food poisoned and are throwing up.
