I think Capricorn and Aquarius were removed. Possibly it is one of the pages mentioned in the letters to Kircher.

From voynich.nu:

Voynich MS - Quire 12

Description

Quire 12 contains the remains of one bifolio, which is folio 73. The original folio 74 is lost and was most probably cut out of the bound manuscript. A cut mark is still visible on f75. The gathering mark is also missing, but may be assumed to have been on f74.

Schematic folio layout:




Aries and Taurus have more detail in my interpretation due to being the astronomical ages with the most known history. What would be the purpose of replacing the winter months with dual spring months? To show global warming? I could see that, actually. 

I can't understand your reasoning, though. Can you explain more fully why it would make more sense that way? Drawing spring twice doesn't make it happen. Did they draw it twice because it happened?
