Scicos 2025 Lmint 21 Cinnamon After working on a xcos diagram and saving, when I come back later in another session the connection lines are mangled with extra vertices and wander to random points in the diagram. They are still connected correctly but make the drawing a mess. Once corrected, the connections seems to then stay put. ---

Hello, Can you share your diagram ? S. ---

I had the same issue, but I already know the background. It depends on the fact, in which direction you draw the connection lines. If the lines are drawn in direction of the signal flow, everything is fine, but if you do a connection backwards, from a block on the end to a block in front of it, then when you open the file the next time, the lines are crossed as you mentioned it. So you have to go with the flow 😉
