Circle and Line was migrated to reference based points. This obviously make that tools that depend on it, to crash if they will not use the same constructs (like circle will use direct point instead a reference to an existing point).
The places where this code which fails were around (and now are fixed):
- face picker feedback (a circle that shows the plan you're in)
- some actions will have a skeleton to be fixed that they are dependent (here is about the Arc actions)
- another action (Extrude) have a skeleton that will be developed in future to be smarter, right now the skeleton code is here, but more will follow in another blog post
