There’s a bug lately where you pick up the last objective on trainyard, if an enemy places a proxy mine down before the package spawns, that mine becomes invincible to gunfire. It will still blow up if you go near it, sometimes it hurts you, sometimes it does no damage at all, but you literally can’t shoot the mine with your gun.
Super annoying. Slows the process down quite a bit too if you’re planning on doing a quick rush because you know the enemy team is dead.
Pretty easy to reproduce too. Hopefully it’s not too hard to fix.
