Windows randomly become not bullet resistant

Hi,

I am really new to using zmod and wanted to try make windows on a vehicle bullet resistant. I have managed to achieve it by setting the windows in polygon mode to car_glass_strong and adding the bullet resistant flag to vehicles.meta.

However at random points one of the windows will become not resistant meaning the first bullet can hit the player inside. This issue seems to vary and changes on what window it happens on

that even happens on default bullet resistant vehicles (example: armored Karuma) and i dont know if it was ever changed but you used to be able to snipe ppl out of the tanks.

im not sure if you can make it 100% bullet proof

So that even happens on default cars? It’s almost as if sometimes the collison on the window stop working but its happening for multiple windows so like sometimes 3 windows out of the rest you can instantly shoot through. It just feels like something is set wrong
