pl_Goldstrike - A bad payload map

This map is the first real map i've been making since May 2018.
The developement was a real mess, being a real noob to mapping, this map is heavily flawed.
"Why is it so "detailed" for a a1 ? I wanted to move on with the map, i've done what I wanted, the only fixes are going to be gameplay wise, at some point i'll go and just fix everything else. This map will be discontinued.
Where do i install the weird "bsp" file :
Steam\steamapps\common\Team Fortress 2\tf\maps

 

Looks very flat. Give that cart path some height variety
