The Automobilista 2 Flag System specifically does not work in offline mode.

Flags are on the developer's radar. I believe that it was planned for 1.6 but had to be put on hold for more important aspects of the update to be done.

 

If you're referring to marshalls flagging on the side of the track I believe you're correct, however this discussion is about Yellow Flags (for example) not appearing on the HUD in v1.6 when they did previously in older builds.

 

Have the devs said they were looking at adding animated flag Marshall's? Would be fantastic.

 

I thought they had once? Maybe I'm misremembering...or getting confused with another racing title
