Issue description
Hi
I have noticed today an issue with the clinic.
My clinic is set up as below with Medical supplies 1 at the top and 2 at the bottom.
The clinic is only giving the benefits on medical supplies 1 and not consuming medical supplies 2 at all.
So only receiving 15 health bonus..
See screenshots below


If I completely remove medical supplies 1 from the building medical supplies 2 are then consumed and benefits are seen.
See below


I have not tested if supplying both medical supplies in separate buildings provides the benefits of both. (yet)
Edit: I did try 2x clinics (one supplied with medical supplies 1 and the other with Medical supplies 2)
It seems that with this configuration the game consumes both and gives an "Average" of 18 health.


Expected behavior
I would expect that if both are supplied the either only the highest one would be consumed or both would be consumed giving the bonus in an additive way (35 health)
