This is going to sound weird but I figured out why my ettins have so much eggs despite there being only one male ettin. They're been mating with other female ettins. I haven't installed the CCSF 2020 Fem patch so I have no idea how this is happening. Is this a glitch that can happen with C3/DS?
I understand why my nonbinary darlings can sometimes mate with male or female creatures; it's buggy but sometimes babies happens.
I have so many ettin eggs.
