Hello,

As the Subject indicates...

I haven't seen this mean much of anything so far, but perhaps I am missing something...

Regards.

Well, it depends.

If it's on a resource, they might want to buy it (or take it, be careful with the huns)

If it's on a city, well... You might want to be careful protecting that :)

Thank you. Typically I see this marker on "not much of anything". I have attached an example of what I mean. 

But, typically, these markers don't point to anything of importance.

Hi johnyoga,

Ah, thank you ZanAlex...the reason for these markers now make sense.
