The Tube Shredder tends to be quite ineffective at destroying the new derby tier 4 vehicles, as the P1000. Ratte would be, because of the pole in the middle of the blades getting on the way, as the new vehicles are way taller than any other vehicle in the game, so my suggestion to abroad, and fix this is diable the colission of this middle pole, as it would allow the new tier 4 vehicles to go pass through the blades easier.
