Breeding

What's the issue? Please include any error messages you receive and as much detail as possible.
My double uterus lion was bred recently to two studs and is due to give birth tomorrow.

However she has two mysterious 0 month cubs show up today (same two studs), which weren’t in the daily message so I didn’t notice them until now.

She is still pregnant and is due tomorrow.

I informed modbox of this and they told me to post here. I'll update tomorrow when she gives birth (a second time?)

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
