can't save lot to library

I am trying to save a lot to my library (not to the gallery) and i get an error message saying the gallery cant complete my request every time i attempt to save

i took all of my mods out, tried to save the lot again and i got the same message. i also reset my sims 4 folder and still have this problem. i haven't tested whether this happens on every lot, but its happened on the honeydew fields lot in britechester every time i have tried to save (even with the new save and game folder) and on one in chestnut ridge although it did save on the second attempt.
