Plutonium

Hello, i've found the map OSG Freight on a old topic about a collection made by someone, as for now i'm not sure the creator is still active on the forum, i ask for help about something, when in game we call a Care package, the CP are not solid, we can pass through, and i need help to make that solid, if there a tutorial to do it i can try it myself, but i'm not a good moder All i know is i got a script error about a clonebrushmodel thing.
If someone can help i can submit the map compressed to check it , thanks
