In v8.2, I had a pre-op plugin that would update a few of of the locked fields on the quote entity (freight, tax, for example). Once we upgraded to version 9, those fields no longer update. The plugin doesn't throw any exceptions, and if I point the plugin to custom temp fields, it shows the calculations that the plugin is doing is in fact happening, it just can't update those locked fields anymore. Is there anything I can do about this?
