Just a few things, whenever I load up a counter-strike map in singe-player sandbox, I delete or move some of the props. When I save the map and then reload it, the props that I had altered are back in their same positions, the props that I had put in their place are still there but they have the original map props colliding with them. Any fixes?

Also, I want to play some HL2 maps without all the npc’s and entities. But when I try cleaning up everything in the utilities section, I just respawn and everything is still there. When I manually remove everything, it’s good for a while until I reload it, then everything just resets. Any fixes?

Finally, the paint does no longer spray on the map itself. Only on props. Any fixes?
