just noted that in reply to my post but repeat here: yeah I was wrong, I happened to look back at Maiſter and my bad eyesight and the resolution made it look like the long s had a crossbar from the t next to it in the default font.

on edit: this was probably where my problem generally was, in lest and Maister and anything where the long s is next to a t it looks very like an f to me, although if I zoom to 170% then it is clear, however at that size it introduces its own reading problems; unfortunately my reading glasses are broken so I just struggled at a lower resolution.
