@crocobaura I have massive OCD, like it controls my life. So I couldn't let this go. I conquered curved walls! So, I came here to tell you... "I stand corrected and you were (was? LOL OCD induced insomnia has my brain foggy) right! It IS possible to create lots with curved walls and no issues. You just have to step outside your normal box and think about building differently. I've been building since 2015 (just because I never posted here before doesn't mean I haven't been around since then... I joined in 2015!) and it's like teaching an old dog new tricks.
I'm currently updating my New Orleans (Willowcreek and Newcrest) and couldn't be happier with the results. I'd share screens but I don't have an image hosting.
