Major bug! Player, world props, entities almost everything randomly turning invisible

On my Garry’s Mod DarkRP like the title says, almost everything turns invisible there’s no particles or anything people just standing around then it happens. No warning, no anything no error. It’s pretty frustrating…

This usually happens when there’s too many entities.

It’s a DarkRP there will always be that many entities. I had 50 people on the server at one point and it didn’t do it then .-.

Im not a dark rp player, so I don’t know the details on how they work, but at any point can people spam trails? This will almost always do it.
