ROBLOX terrain will create a massive amount of contacts on the client-server mode only in the client server mode. This can be easily reproed in ROBLOX studio.

[li]Open up ROBLOX studio[/li]
[li]Open up a new place[/li]
[li]Generate terrain, default settings[/li]
[li]Test Server with one player[/li]
[li]Check contact count in diagnostics — It’s around 16k for me. On the server it’s around zero. Somehow the anchored baseplate is generating contacts with the terrain, only on the client model in server test mode.[/li]
[/ol]
Both parts are anchored. Shouldn’t there be zero contacts?
This bug seems to be generating a lot of lag on the physics end, and happens online with regular terrain on anchored parts.
