Do you want to set the Weapons Crate Probability of all the Weapons?
Keep in mind that the "Super Weapons" group is not displayed in the Crate Probability settings... because there is another special button to enable them as a single bunch and this kind of Weapons shall spawn randomly in the game.
I took this quotation from v3.8 readme. I think that's the only glitch we are all talking. The quotation says that the glitch was fixed for ground weapons in v3.7.2.1, and only in v3.8 the glitch was fixed from weapons dropped from rope, chute, bungee and Jet Pack.
When the weapon is fired, even when you target it, it goes according to the momentum of the rope (think on homing missile or pigeon), and only after aproximately 1 second is that the weapon is triggered to follow and hit the target. The thing is, when you fire a weapon without targeting it, it automatically is targeted to the center of the map. So, the behavior of the weapon is the same as if you had clicked at the center of the map.
After v3.8, though, the only way to perform this glitch is first clicking at a target with the weapon and then you can change weapons, walk, jump, rope around, use low gravity, etc. and before your turn ends, you can make the glitch and it will work, but the weapon will go to the point you clicked at the beginning of the turn.
