I had a similar problem. Thing is I only had the first part of the error the one in 1131 without the 2014. Now i found a temp solution to my problem, this is a really dirty fix and will probably only work if you are playing as a male. In which case all the broken kids will be yours now. Congratulations (my relatives window is starting to look pretty ridiculous)
in your global.gd file before the line 1131(game folder not appdata)
mother.preg.womb.append({id = father.id, unique = father.unique, semen = cumprod, virility = virility, day = 0,})
paste
if father == null:
father = player
your lines 1131;1132;1133 should look like so
if father == null:
father = player
mother.preg.womb.append({id = father.id, unique = father.unique, semen = cumprod, virility = virility, day = 0,})
I haven't really proof tested it, just went 80+ turns and impregnated 2 slaves. no error so far. It might cause some pretty nasty stuff later on. ill give it some more testing later.
