Thrushcross Grange is an accurate recreation of the glyphs from a beloved 1970s record cover. As a result, it has a number of issues with it, as it appears to have been nothing more than hand lettering and never intended to be a standing font at all. At the request of the person who had wanted it, I intentionally kept the issues in.
If you would like to see a more modernized version with all the bugs worked out, please let me know. The problems bother me as well and I'm halfway tempted to make a "pro" version someday that irons out all the kinks.
