Cum-Amount altering Genes make Pawns Infertile with Menstruation

[vegapnk]

Following report from Discord:

I  want to report a incompatibility. 
If a Xenotype has one of the "more cum" genes it will break RJW menstruations cum detection.  
no matter how big the gangbang is and how often they get vaginally bred there is no "cum" to get pregnant from. 
I scoured my player log and the hugslib but i could not spot any error relating to it. the load just dosnt get added to the uterus.

and for RJW menstruation -> no cum, no chance of pregnancy.

We still discuss this in the discord, some users seem not to have it, and some seem to have it only for the first sex.

Update --- Error Log:

i think my problem lies in line 4588 : ("Fox" is the name of the pawn that bred vaginally (futanari)

So this seems to be a more general issue, soemwhere else. It is fun documenting things, but I don't think this is in my domain.
