Hey misutow0lf,
Couple of tips for you:
Generating waypoints for the bots is as easy as typing nav_generate into the console. You can also turn their difficulty up by typing bot_difficulty 10.
What happens is, CSGO only generates a nav mesh automatically if you don't have one for that file name. So if you change your map name, it will create a new one automatically if there are bots in your game. Otherwise, if you move walls or structures around and don't change the name, bots will run into walls unless you generate a new mesh.
Bots aren't that useful for playtesting a map but they may sometimes use routes or areas in the map in an unexpected way, which can give you a new way to look at your map.
Also, the radar needs to be packed into the BSP file for other players to see it when they join the server. This can be done in a number of ways. You cna download PakRat, and try that out. But that doesn't work for me for some reason. So the other way to pack it into your BSP is to upload the map to the workshop, which will do all the packing for you if your radar is in the overview folder and named properly. Then you can download your own map from the workshop and upload it elsewhere for RZL to host during the playtest. And your radar should work fine.
I've downloaded your map, and I'm gonna go have a run around in it.
