Don't put a parcours , it's.... lame, impossible with any non jumping classes, and isn't "legit", keep that for a joke map.
It's very dark, i recommend trying to make everything outdoor to help.
The way to the parcours is just a vent, and it's lame too, make so flanks go from a point to another, and not from last to mid.
During the imp, the map broke, we couldn't even play it, so make sure the gamemode assets are not changed from any prefabs.
Not trying to be rude btw, just trying to help.
