Steps to reproduce the behavior:
Reload UI

I am able to reproduce this, seems likely due to the recent API changes in the prepatch

So far in my testing, outside of the initial lua error, I am not seeing any other impact to functionality.

While I continue to work on a fix, please let me know if you notice any other impact related to this
