Have you tried deleting the bowling lanes and putting them down again?

Well, I went and tested a Maxis bowling alley from Downtown and it’s the same story there as well. I’ve never built a bowling alley before, so I was wondering if it was something I did wrong. Just poor lighting, unfortunately. 😦 

Overhead lighting doesn’t illuminate it at all. Floor lighting (such as the garden lamps) does, but then it casts weird shadows on the Sims. Can’t win. 😦
