That's strange, nothing should have affected it. Did you check the force 2.0 checkbox that was new in 0.26? Try changing it and see if it works

Cool, glad it worked :)

This is a silly issue I should fix

No, you'll either have to use two values or a Vector4. (This is due to Unity limitations)

While a grid would perhaps be neat, I think the snapping system is good enough as it is. A grid may force me to make sure all nodes are made to fit the grid, which may be a bit too restrictive.

Let me know if it worked, in which case I'll close this topic
