Because bad bug in high fidelity. Instaling under different user account also install sandbox under the administrator account.
I mixed things up, and by accident overwritten the wrong domain. instead my localhost sandbox i did update my simsquare one. restoring models.json seems not to help.
So just curious how you restore the backup high fidelity made when updating the content in sandbox ? I suggest to stop asking that questio. and add seperate update content option in the menu.
Meanwhile. going to fall back on backup. Good test to see if that works.
Note ADD: Domain restored by my other automatic backup
