Damn, didn't realize how much you had going on in your life right now (I just figured you were generally busy)... hope you're doing alright, especially given "deaths" being included :|
As far as pregnant slaves' boobs, I hope it'll also be a little less extreme? Most women just gain a few sizes while pregnant IRL. Though (regarding it being temporary) they don't always lose all of them afterward, either - you could make them have a maybe 30% chance of ending the decrease a single size bigger than they were to begin with.
