When I posted an reply at Special:NewMessages, after saving the page was reloaded, but my reply was not shown in the thread, and in addition the message I was replying to had disappeared. Moreover the other threads started looking weird. See the <s>attached</s> linked screenshot [1]. Reloading the page does not fix it properly [2].
