For some reason the wings are not working in missions?!
They "lay low" & does not have the feather-flames.
I was check some display/video settings & re-equip it, played different missions, same thing.

So i open this thread to find out what is about, i attach a screenshot as well:

Update: gone to relay & in there it works like in the spaceship:

So any idea why looks different while actually play?
Found the answer myself: while i did a longer bullet jump i seen that they opened, did a flight & more longer jumps and looks like they light up only then, which it's make sense & make them work more than other static syandanas that's why i expected to be as the others.. and less real as they actually are.
