Help?

Yesterday I added Takemizu Village and Three Lakes to Mayberry (Twikkii Island already exists, it’s where Angelino and Carmen spent their honeymoon). 

I just sent a couple to Takemizu (after first going to the hood to add pool tiles to water lots, no issues encountered) and when the couple left home, the load screen came up for Takemizu and then after a couple minutes my game crashed. As mentioned, I’ve sent Mayberry sims to BV hoods before so not sure what the issue is. Any help or suggestions?

I did recently follow @meetmetotheriver ’s stealth hood disablement tips, might that have anything to do with it?
