Vehicle inventory..?
Some players does that including me, but most of the players don't and doesn't have the knowledge/expectations that they can lose their weapons due to server bug I never lost weapons since 2012 until 2020 I never used vehicle inventory until I lost 9k of grenades which made me believe that it can happen for me again that's why I chose vehicle inventory.
It's an MTA bug, for some reason in some extremely rare case, the client tells the server it has no ammo and only seems to occur with projectiles. I thought there was a lowered projectile carry limit to prevent big losses.
