I've noticed recently that users using the visual editor occasionally remove the entire gallery section of an article. This is very problematic as it can cause a lot of hassle trying to fix the issues caused by this whilst still maintaining the actual user edit.
I cannot get the visual editor to work on my computer for some reason, so I don't know if this is an accident that several users have made, or if it's a glitch with the editor mode. Can someone shed some light on this?
