build_buy better exceptions error

Hi kristensims4​ 

yes, it's here now. Guess it was eaten by the spam bot.

Seems like an issue with the household inventory of the household. 

Do you have an imaginary friend in that household ? Do you get the same error on other households ?

Did you get it now? i sent it three times now lmaoo

No. Please post it here. You need to upload to a third party site or copy/paste.

Please remove all your mods, including BE.

Then trigger the error again and post the LE the game throws and not the BE version. You can find that in your documents folder.
