Small World Editor Bug

When I am using the old world editor, and hit CTRL+Z to undo some of my most recent changes, my roads completely loose their spine/nodes.
They are there, but aren't being displayed.
It just becomes grey and the spine/nodes are gone.
is this a key binding issue?

 

Sure thing—-
I’m currently in bed but will get it to you in the morning.
It wasn’t a big issue, just something weird.

 

ok...
its not doing it anymore
i have had the issue in the past- but now it wont re-appear.
maybe its not CTRL+Z thats causing it?

I'll keep digging.
EDIT:
Im a big dumb stupid.
its toggling the show spline setting in the roads menu. and its just Z that makes it happen.

Its not a bug, just me being an idiot.

Im sorry @Nadeox1 for wasting your time.
