Cannot name a sheep "Grapes".

I tried to name a sheep "Grapes" but I can't, because the game tells me it contains a word some people find offensive. I know what word this is, but that kind of swear filter is a [clbuttic programming mistake|https://thedailywtf.com/articles/The-Clbuttic-Mistake-.] 

Then the game happily let me enter a common slur used to refer to transexuals. I get why you don't want to let people use the word "rape" in names, but maybe "shemale" should be on the list? (I made it private because that's a horrid word used by horrid people and I don't want someone else to see it.)
