Why would you want to mod?
I think this was discussed before. In VC col fixing = modding. In LC col fixing = not modding. The whole LC is a mod, and countless of roofs have been fixed there, so fixing a pointy thingy sticking out of a building shouldnt be count for m0dd1ng
Jaik just play in VC map the way you know it, finding a new good spot will always bring more positive feedback than landing a fixed collision stunt.
