grayed out for unknown reason

[Gus]

Layer is unlocked
Reserved element from teamwork
Still Gray?
Any other reason this could be gray?

If it's a composite wall it's problably the line pen color.

Thanks for the idea. It's not the pen color though. If you click on the image, you can see that it's a grey dot at the node. Also, it cannot be edited. I tried to reserve and unlock it in every way I could think of, then I "reserved all" and I was able to edit it again. I still have no idea what was reserved though, that allowed me to begin editing it again.

Something from a story below from Trace?
