For me, openIV says something about a fatal error when I try to use the package installer. So I downloaded a new 'vehicles.meta' but it didn't work this is from the end of the log -

{
New line: " <modelName>POLICE_OLD</modelName>"
Search for: "*<modelName>POLICE</modelName>*"
Search condition: "Mask"
Line Index: "-1"
}
