Touchstones won't reload

When I edit a post with lots of touchstones (say, more than 30), the touchstones often won't reload. When the post has a very large number of touchstones (say, more than 60), the touchstones won't reload ever. I've tried going away from the computer and coming back half an hour later, but it still doesn't work. Needless to say, this is very annoying.

Once in a while my posts with large numbers of touchstones will reload, but most of the time they won't. They won't even reload if I delete one entirely and re-type it, or if I copy the text and paste it into a new post. I'm also having trouble with author touchstones, but maybe that's covered in another thread.

I get that too. And author touchstones are covered here.
