The fact is that after some time the plugin stops working on boxes in built houses, new created boxes have a button, and the old ones do not, I do not see the sequence and tried to test in different ways, I understand what you are talking about, but I think that the problem is not with me alone
You are the only one having this issue. I can't fix it since I can't reproduce it.
Try to check if you are the owner of entities with this plugin, for example.
Merged postSimpleSort works fine under the same conditions but I don't like the button layout
