I’m sorry to say that deleting nodes or making them into ‘off curve’ makes the curve go badly out of shape. Glyph making is therefore much harder to do than in the earlier builds. Bitmap import is much better, though, but if I can’t use the nodes like I could before, I’ll have to go back to an earlier build.
Previous versions behave the same, so there is no need to go back to an older version.
I don’t see this problem. Only thing I can think of is that you turned on snap to grid by mistake.
