the answer is :



sv_cheats 1;ent_remove_all prop_physics_multiplayer;ent_remove_all func_physbox;ent_remove_all func_breakable;ent_remove prop_vehicle_jeep;sv_cheats 0


paste this command to your game console and it will remove all default map props on the map and remove the breakable things and the jeep next to the lake

i recommend you do this before you start spawning anything just in case it gets deleted as well
