Closed bspline node duplicates itself unexpectedly

Asked by Discrete Games on 2018-04-06

Often when I'm tweaking the nodes on a closed bspline path, the node that was the original start of the path will duplicate itself in place unexpectedly, messing up the path curvature (but keeping it closed). It does not always happen, in fact it seems fairly random if it will or wont, but it is quite frequent.

Here's a video of what I mean:

See how at the 42sec mark I move a node and another node duplicates itself in the path. It happens several more times.
In the video I was only using left-click. I did not double-click to add any of the nodes that somehow appear.

I'm using Windows 10 with Inkscape 0.92.3 (2405546, 2018-03-11). It happened in 0.92.2 as well.

To me this seems like a major bug. Shapes I'm making unexpectedly get weird angles in them. Deleting the newly spawned nodes doesn't help for long since they'll invariably be spawned again. Is there something fundamental about bsplines that I'm missing?

Thank You
