As far as I've understood the sistem, waze does moves segments and nodes around based on the gps tracks. This means that roundabouts will move away from the center of the circle on the satellite, and in certain cases where GPS coverage is less good, will even become slightly oval or completely dead like the first link I sent. And when this happens, the dozens of nodes of the original roundabout becomes much less, like you can see on this one.
I've never seen any evidence that Waze moves segments or junctions outside of a roundabout, but I've seen exactly what you're talking about and wondered about it. Has anyone else seen roundabouts conform to the GPS tracks?

Conversely, is there a way to force roundabouts to no longer be roundabouts? Sometimes the fastest way to draw a roughly circular or oval road would be to start with a roundabout. But I don't want to screw up the TTS.

I seem to remember that, at the time when waze changed the meaning of 'Lock', that it was also stated that the auto-adjusting of segments was being removed. I haven't done a forum search yet to confirm that.

On those roundabouts, I am not seeing the center node. Are you deleting them?

There is a roundabout I looked at before replying in WME. At certain zoom levels you can see it.

If you zoom in and out sometimes you can see the center node.

Thanks. Odd that there are soft turns when that is not a basemapped roundabout.

Yup, first thing I got. My sloppy editing in old I suppose.

I wonder if it is related to an issue we stumbled upon where roads were changing direction. There is a 2 mile segment near my house that I am the only one I drive on, and I only drive on it one way. I made it a 2 way way back in march, and it has since changed to a one way, switched it back and same. This happened three times. I have gone ahead and killed the entire stretch and rebuilt it, and am testing to see if it does it again. So far it hasn't, however every few days or so when I drive on it I get the pac man.

It has been reported to Waze devs and they are looking into it.

The second issue is that the bridging increases the level, and it may happen that a roundabout with different levels per segment may confuse the routing and give wrong instructions.
I don't believe that having 'backwards' segments on a roundabout will necessarily cause problems. I've been looking at a few, and found them appearing on roundabouts that otherwise route just fine. I'm still investigating it some more though.

Levels have no consequence on routing at all.
