That's the thing, the heads up displays say they need materials but when I check with ASAM they're not ready to upgrade, no option to. That's why I wanted to ask.
BTW some of the buildings lost that icon when I refreshed the plot, I guess it may have been a temporary glitch.
So to sum it up, that Icon only appears when an upgrade is available and not enough resources right?
If that so, then yes when you manually upgrade you can see the needed items.
