Traffic Light tools became unexpectedly unresponsive at specific intersection

[AllegedlyLuca]

For unknown reasons two of the traffic light tools aren't working on a particular intersection in my city (add/remove light work as normal, but not timed lights or manual light operation). The tools work as-normal at other intersections.

Attached are the output_log.txt and TMPE.log. I did have a look through them, and when I attempt to add a timed light on the intersection in question I get this error:

Could not identify any errors in TMPE.log, though there were a few lines indicating inability to find a segment. They only appear a few times, and don't seem to correspond with the errors from output_log.txt that I'm aware of.

If necessary I'll provide a copy of my city too.

If necessary I'll provide a copy of my city too.

Yes, please share URL to save game.

Also, please indicate where on the map the issue occurs (eg, with screenshot or describe nearby landmarks or something)

Area where issue occurs:

Edit: Restarting the game appears to have ceased the issue. Still something to investigate though.

• The only chance to get a NullReferenceException in MarkAsUpdated() is when geometry is null.
• It seems that segEndGeo is not null but segEndGeo.GetSegmentGeometry() yields null (in GeometryManager.MarkAsUpdated(NodeGeometry, bool))
  
• So, I guess the node geometry still holds a segment end geometry that points to an invalid segment

So many mod updates in between, don't remember any other reports. Create new if you spot something. Closing... 😉
