The Shimmer by QWIRL lamp from Business & Hobbies seems to have a wrong footprint: even if it's small, placing it on a table make it impossible for Sims to eat there, as the lamp seems to take-up all the room. It can be seen when placing the object (compared to a similar lamp from Lovestruck that doesn't block Sims from using the table):

I haven't seen a collection thread for this kind of issues, so I'm posting a separate topic.
