Please do not use Entity Scale Manager v3 yet. Drone Scale Manager needs to be updated to work with it. I also found that it will probably not be possible as the native scaling method doesn't resize drones properly.

Please use Entity Scale Manager v2 for the foreseeable future if you are using Mega Drones.

So far, no plugin requires ESM v3. Monument Addons was updated to be compatible with it, but v2 still works.

Perfect, thanks for the heads-up
