            for j,l in pairs(v.items) do
                local hash=GetHashKey(l.object);
                if(not IsModelValid(hash)) then
                    print("Object is invalid: " .. l.object .. " | Hash: " .. hash);
                end
            end
        end

Concrete example: v_med_p_sofa is invalid, but p_v_med_p_sofa_s is valid.

I am wondering if this is expected behaviour (i.e.: old objects being removed to make space for new ones?) or an actual bug?
