I've removed content from previous edits but got no warning about that.
:Yes, we discovered this during deployment. A priority right away, certainly!
I "lost" my edits due to a mid-air collision. Currently there appears to be no mechanism to detect if someone edits a text which you opened and changed and saved before... I thought we have edit tokens
It looks like the editor disables edit conflict handling. As I appear to have ended up overwriting an other user's edit.
