Whats the one mistake every new SAND player makes?

I feel like everyone has that one moment where they realize they been playing completely wrong 😂

Mine was thinking i could just "quickly" loot one more building before heading back...

Ended up hearing another Trampler coming over the dunes and lost basically everything lol.

Curious what everyone else's was.

Could be a bad loadout, trusting another crew, getting too greedy, forgetting supplies... whatever made you go "yeah im never doing that again.
