Can't quote/report posts sometimes
There’s another thread about the missing icons: https://forum-en.gw2archive.eu/forum/support/forum/Some-threads-have-no-edit-quote-report-options/first#post151480
As for the post/edit box, most of the time there’s a small grey icon in the bottom right corner that you can click on to drag and re-size the box. But sometimes it’s not there, possibly related to the missing edit, quote and report icons?
