Some 'invisible spawn point' buildings are unselectable

[originalfoo]

I'm using the Invisible 1x1 Spawn Point Variety Pack from Steam workshop, and most of the buildings work fine; spawn points can be edited.

However, I've noticed that for Fire Truck and Disaster Vehicle (both the road variants), the buildings cannot be selected for editing.

The buildings highlight when mouse hovers over them, but clicking them has no effect:

Also, if I select the building and click the spawn points button in the building info panel title bar, it activates the spawn points mod but with no building selected:

Again, from this mode, the building will highlight when hovered, but clicking has no effect.

Output log attached:

There's a load of exceptions at the end of the log, for example:

Customize It: Extended settings for the fire engine spawn:

and the Disaster veh spawn:

Edit: I'm also using Service Vehicle Selector 2 mod which hasn't been updated in a very long time (eg. it struggles to tell difference between helicopter vs. road vehicles of service buildings, and some service buildings it doesn't detect at all - eg. vacuum pump service).

BTW, these spawn points used to be editable with the Building Spawn Points mod - so maybe it's a mod I've recently started using?

Following mods recently subscribed:

• RON
• BOB
• Curb Height Adjuster

I'll try disabling these next session and report back.
