Breeding timer Edit

There is a breeding timer in the Settings that will show the current time required for Trimps to breed back to 100% after sending out a group of soldiers to fight. With enough Geneticists, one can stretch the breed timer to very large times (even infinity), but this is not recommended since one only needs a breed timer of 30 seconds for maximum Anticipation stacks.
