Smaller sized milk bag absorbs larger sized milk bag

[billy96]

Even though the milk bag can't be used directly in your inventory, apparently it just absorbs large sized milk bag to the one you used. The milk bags were acquired with the help of JoyCo's Magic Milker 7 that you can buy in Mhenga's clinic.

Example:

1x small, 1x, medium, 1x full
steele "uses" small
now there are 2x small, 1x medium
steele "uses small again
now there are 3x small

Example 2:

1x small, 1x medium, 1x full
use medium
1x small, 2x medium
use small
2x small, 1x medium
use small again
3x small
