Has anyone run into issues where the Grid Layout configuration gets lost, and the website isn't able to add anything to the grid editor. Any existing item added shows an error saying "Something went wrong with this editor, below is the data stored", and then shows the grid config value.

This doesn't affect the front end at all, and after a restart, the grid editors work as expected. It also only happened occasionally, and we have been unable to determine why it is happening, or make it happen on demand.

We suspect that it might have something to do with the Nexu package, but mainly because the error started to appear about the same time we added that.

Also most of our grid editors are created using DocType Grid Editor, but we do still have some old LeBlender editors as well, so I'm not sure if either of those could be causing this.

Has anyone else seen this?
