Partial grid editor being returned from Umbraco backoffice

[rickread]

Hello!

For our Mind website, we use LeBlender with the Grid - from what we can see this updates the grideditors.config.js file with new editors we generate (natively or with LeBlender), and these are called in by the backoffice with the /umbraco/GetGridConfig api request.

This appears to work well, however sometimes (not every time) when the website recycles - the call /umbraco/GetGridConfig only returns a partial configuration, meaning the grid editors generated with LeBlender fail to load in the backoffice. We noted our installation of Umbraco was different to the NugGet installation, as the directory path in our version was using a lowercase 'config' directory (now updated to 'Config' to match the installation), as we thought this may be the cause in not being able to read the grideditors.config.js file. From your experience, is there anything else that could cause this or have you had any other reports of this occurring before?

We are using Umbraco 7.13.2 and LeBlender 1.0.9.2

Many thanks
Rick

To add to this, I've noted that the grid editors being returned when this occurs appears to exclusively be from the app_plugins directory
