What does this icon designate?

On my players combat tracker, they get the running man looking icon, instead of cards.

What does that icon designate, it is named indicator_flag.png....so what is it indicating?

Gonna throw another question out there, maybe someone in this forum will know before I post in another.
When a person modifies or creates extensions that change graphics (icons or fonts), does FGU overwrite the graphics in memory, or load all of it into memory, the old and the new graphics?
I understand loadorder, but I was curious about the memory usage.

That's the on Hold Icon, I assume you are using the Beta FGU?

It's a bug.

Thanks for the answer.
Yeah, I am running FGU ultimate.
That icon had never shown up in my testing, only when I tried to run a game. It really didn't affect anything, but was annoying not knowing what it was.
