Dupes don´t get sick

After Update 324351 they finally got sick.

When the q3 beta started, I experimented with 10 duplicants.
There was food poisoning in every foods, and there was a slimelung in every oxygen.
Only one dupe suffered from food poisoning during in 30 cycles.
The slimelung that suffered for 2 cycles had an average of one or two dupe always.

If you'd increased the number of duplicants, you'd have a different conclusion.
