note: I only did this as I have the game via family sharing and it won't let me comment directly on the workshop comments

That's definitely not a feature, and this has never happened to me when using any pieces even mixed together. Can you perhaps upload an output.log or give me any errors that might have shown up?

Ultimately I can't really guarantee how the mod works aside from normal subscriptions on the Steam workshop, but I can definitely try to diagnose the issue.

@elektrix can you controle if you place a road and use the mod and remove the road again that ifit is removed that those nodes are not visible but move it shows that their are nodes, can i send you a pic for more explaination?

When you click the mod's button it should be clearing the array of nodes, making this behavior impossible. I'll take a look tomorrow as I fix other bugs in mods and work on assets.

The icon of new version blocked the mod "Climate Control". The both got same location of icon. And you can't check "Climate Control" icon and open the panel.
So, you need make a moveable icon, that's more better than a stop icon. Or change the icon to right of "Climate Control" icon or back to first version location.

And you should change the 'Node Select Color' from black to "Custom Color" or a light yellow, light blue or light green. That's because the black color is hard to see in day time and almost or can't see in the night time, and it make you hard to know how many node you have selected or don't know what node you have selected.
Or add a function like a light green 3D point up the selected node.

icon is now locked near the left centre of screen since the update - cannot be moved.

Double clik the icon to enter move mode guys, then drag the icon where you want it. The new position will then be saved for future sessions.

yep - was updated a few days ago.
