Players Fall Through Map

So I have noticed many complaints from players in my sever that everyone seems to fall through the map when playing on normal settings and I have tried everything that i thought of I even put my server in resource by resource and that was no help this is what players get when they fall through the map.

I don’t know much about servers but it could have something to do with having two many resources in a server that cant handle it. You could try optimizing the textures. It could also be a specific resource that just doesn’t work and causes it. I had a problem with this on one of the servers I was a dev on.
Hope this helps, and good luck fixing it!!

I Know i fixed it already i only have like 150 resources
