TT Hinting sometimes anchors don’t work

Every now and then it happens that the TT hinting in certain glyphs doesn’t work. In my current case for example the glyph “two”. When I add the top anchor, it doesn’t move the outline to grid. Surprisingly, when I move certain points (in this case the the two top left points), the anchors moves the outline correctly.

Can you send me the file?


I found the problem. Thanks for the file.

Same here
