There is an issue with broodmares in SO8,where the history of offspring exceeds the number that is realistic.Example if a broodmare is less than 7 years old,it is impossible to have given birth to more than 3 foals.Some of the offspring in the game well exceeds the possible amount.

It's no different than SO7. I suspect it has something to do with maintaining the size of the horse pool.

The unrealistic number of one broodmare giving birth to multiple offspring was corrected in SO7.I am hoping it can be rectified in SO8

I'm running SO7 with the latest patch, and while broodmares are no longer foaling four and five times a year, many are still producing two offspring annually.
