Have you tried turned testing cheats on and resetting the bug boxes on that lot?
And, If you would like, I am willing to test the lot. If you will upload it to the Gallery and post here when you've done that with the lot name, I will download and test it to see if I can spot anything that might be causing the issue or find a way to fix it. If you don't want to do that, that's fine.
Hope this helps.
I tested this and got exactly what you did in a vanilla test game, 2 of them in fact. And I have come to the conclusion that something is not right with the lot itself when it comes to the bug boxes.
During my testing, I found some strangeness with the lot elevation compared to the surrounding world but flattening, bulldozing or using the terrain tools made no change in regard to the boxes. I tried with multiple sims and on multiple levels of the house and the boxes would not work anywhere on the lot. I have never seen anything like it. And I only found it with this one object which worked perfectly fine on every other lot I tried. Every other object I tried worked fine.
I also tried bulldozing the lot then going to Manage Households and then back to the lot and tested. And then saved and exited the game, reloaded and tested again. Still got the error in both cases. The reason I tried that is because that lot uses the curved porch sections and those act very similar to platforms. If you delete a platform, they still leave some type of residue behind that prevent you from placing anything in the tiles where they were. The workaround is usually to exit the lot and come back. I have tested issues with those porch sections before too. But not in this case. I still got the errors.
After testing this in a vanilla game, I then went to my main save where I use mods and cc. In my main save, I have played that lot extensively and it has 4 bug boxes on a basement level, 2 stories down where the garden is. The last time I played the lot was not too long after SE but before Paranormal and the kits. What I found when I got there was that the bug boxes were all empty and that no sim in the household could access them. They all got the routing error. I am pretty sure that when I last played the lot, that the bug boxes had bugs in them, but not absolutely certain of that since it's been awhile. I also checked a few other lots where I have them and they all worked fine.
So in the end, something has changed that has caused the bug boxes to not work on this one lot. So since the bug boxes work everywhere else, it has to be something with the lot itself that prevents the bug boxes from working there.
You can disregard what I posted earlier. I tried resetting and it doesn't work and since I have found what you did on my Cypress Terrace lot, there isn't any need for you to upload yours.
Sorry I can't help you fix this in your game but I hope that what I have related here helps get the issue fixed.
