So I have been trying dumb stuff with bots on the ps4 re release and the tube on Lunarcy that connects most of the map to the sub little area you can actually get out of bounds using the vacuum weapon that removes the enemy weapon and launches them if you rub the exit tube against the tunnel wall. I don't think this matters besides gate relay as you would be running into enemies and you can get trapped if the AI accidentally stack cars to the point of it ruining your run or using the bug to get a better time and less interactions. Since this weapon is the cause of the bug i will be updating this page with map and location with all possible bound breaker.

So in the HD versions of Cel Damage they allowed the advanced movement of cars flipping and stuff (Of course its a given) but if anyone been checking it covers the gap of lava connecting the finish line and the only other gate on the map which is on the other side of the Lava i have tried the "Casual" route the shortcut under the Shmoe (Since its the only thing the map is missing) and the lava it seriously shreds the time by almost 10 seconds (if you perfectly flip each time without getting hit by the lava, not get affected by the other racers and be T.Wrecks since hes the easiest racer to do the strat when going for a run).If you do know this good on you but if you don't i very much suggest practicing this leap as its the fastest way to complete this stage.

P.S I got the whole 10 second thing from the difference from the "Casual" route and compared it to the Lava Exploit and got the best time from both its what i had not yours so keep it in mind
