Object not shown in Objects' tab

[puntukas]

I have an object from ETS 31/0/45 but this object is not displayed in the Object tab. Also I can not add another object with the same address.
If I find ID thru 

Code:

local obj = grp.find('31/0/45')
if obj then
  for k,v in pairs(obj) do
    log(k .. ' = ' .. tostring(v))
  end
else
  log('not found')
end

and delete this object with "grp.delete(id)", and then add it manually, the operation is successful but it again dissapears from the list.

Could you advice?

Thanks

Check if you have some other script that creates the object or it might be created automatically by the bus sniffer.
Object list is not reloaded automatically for externally created objects, you can press reload button at the bottom near the page selection and it should appear.
