Fix: [L5] Auto split loops: bug fix and improvement
I continue to find loops like this one that will sweep to remove and then fix the loop back and forth. Sometimes you can even save in between and it will stop, but then permalink again and it starts the circle again. I messed with a few others doing that process over and over on the same loop with a save sometimes after a sweep and sometimes after a loop fix. Not sure the combination, but eventually the loop stops the cycle and it no longer requires a fix. This one above seems to be in that category so I left it unsaved. I believe the current extra node was added by the loop script by me with 126.96.36.199 today.
Another loop highlighted here will want to be swept right after a permalink, and then the loop process begins like the others above. However the two loops on the map directly above this one did not have the problem until I messed with one of them. For fun I removed the node that used to be at the corner of this segment. The loop fix added a new junction between these segments. Now the sweeper wants to remove the south-most junction. No further saves done here.
Here are two more loops that the loop fix just fixed for me, but after the save and permalink they want to be swept.
For comparison, these two loops did not show the problem described above. The loops needed fixing and never allowed the sweeper to fix the extra nodes after all my attempts to confuse it.
