Zmodeler3 Siren problem - car breaking down

[Phanta 2]

Hello!
I've ran into an issue with the 20th (which should be max?) siren to put in. Everything went completely fine, until I added the 20th. Then the whole car started doing this:

If I remove a siren, the car works fine. It does not matter which siren# I remove. It almost seems like the sirens take over the body parts and scale them back and forth like sirens are supposed to do. I've scouted around but have not seen this issue before.
Also, the moment this issue will occur, all the extra's are automatically spawned, and they cannot be disabled. Also some objects like the trunk are missing.

Would love to hear your ideas. Thanks!

Hi mate, don't know if you still need help with the issue, but from that brief video it looks like a lod issue.

 

Have you had any luck resolving this or has anyone helped privately?

After a week to 10 days after the issue, trying everything I figured it out myself. The problem was that there seems to be a max amount of items there can be in the hierarchy. When you exceed that number, it starts doing really random stuff. I model my cars for FiveM mainly and test them in there, so I'm not sure if it's a problem with that, or if it's a known GTA problem in general, but combining some items that could be combined solved the issue for me. I don't know how it decides to randomly turn stuff into sirens, but another example I got with the problem was that when I added a bobble head, random stuff started bobbling:  https://gyazo.com/1298343af23828c1faba1de0e0544a44
So yeah. That was the issue. Thanks for getting back to me though
