'Unexpected path error' after upgrading house

[sohamtiwari3120]

Hi,

I upgraded the houses in the train subset of the house scenes loaded from 'procthor-10k'. I used the upgrade_house_version.py script for the same.

I however get the following error. Can someone help me understand how can I resolve the same? Is this a bug?

File "main_real.py", line 223, in <module>
    main()

    currect_house = SCENES.initialize_house(
