Failed to compute cost.

Hye. First of all, sorry if I post this in the wrong section. It's my first time posting here. I recently used your fix to update my the sims 4 to 1.20.60.1020. everything works fine. except for the kids stuff pack. Ive been getting "failed to compute cost' error when I'm in buy mode for kids stuff. I can't place/buy them at all. Any help? 

Hello @sarahkirakira and welcome to the forum,

I have successfully placed items from the "Kids Room Stuffpack". Do you happen to have any script mods or outdated custom content ? If so, please try removing them all for now. Good luck !

I do have them. I've try removing all of my custom content, but still doesn't work.

For how long do you play household in which you placed item?

I've been playing with my previous household since before the recent update. I've tried to create a new household and play a new game. But I still get the same error. I even tried to place my new household on different lot.

Sorry for the late reply,

Did you use WinRAR for extracting the content of the new update's .RAR file ? I can place the items for the Kids Room Stuffpack with no problems whatsoever, though my game is arguably 'sterile' (no mods, CC, or any savegame-errors).

yup. i used Winrar to extract them. i think i'm just gonna try reinstall the game all over again.
