We already know about this. I have personally started banning people for abusing it, obviously a slay and a warning would come first.
Just to let everyone know, I had contacted the creator of the map, and he is aware of the glitch. That's why he removed it in famouZ and he probably plans to add it back in famouZ 2 when it is released. I have also asked him for thhr vmf for famouS so I could fix it but he didn't have it so there will be no fix until there is a new version of the map.
We can't decompile it, well, it will break if we do, and parts will be missing.
All in all, this is unfixable unless you get the creator to get a vmf for the map and for him to give it to you. Just try to avoid playing that minigame and just report people who abuse it to skip over things while they have it since it falls under exploiting.
