Hi again Yaron,
Another bug we discovered using MultiPageEdit :
When a template is used with a pipe, it doesn't get through MultiPageEdit and stops parsing the remaining properties.
For exemple, for the word suffixe : https://dicoado.org/dico/suffixe (correct properties shown https://dicoado.org/wiki/index.php?title=suffixe&action=pagevalues)
On Special:MultiPageEdit we get :
Page : suffixe
Def : affixe derrière le radical d’un mot
Classe : nom masculin
Ex : Le mot {{"
and it stops right here, where the pipe should be. No "Contr", "Voir", "Image", "Légende", "Cat" nor "Attention".
