I first noticed it around 0.8, but for some reason it seems like the only vehicle-mounted turrets I can get working are Flamethrowers. Plasma Guns will fire and consume ammo but do no damage, Machine Guns I can’t seem to load (They won’t except ammo from bins inside the vehicle, and ammo dropped on the turrets just falls through.) Fusion Guns I never figured out how to properly load sad to say.
Flamethrowers are wonderful, but they also have a horrible tendency to destroy my vehicle.
I did but I couldn’t figure out how to load it, in an earlier version (0.6 I think?) you just dumped ammo on it and it used it but that causes it to fall though now. As far as the plasma weapon is concerned it fires (There’s a message) and it uses ammo, but it doesn’t emit a projectile.
