Limit how many objects each player can place (protocol 43) - Servers and lobby hosts set how many objects each player may have placed: object_limit in ReSkateServer.json and the "objects" command, "Objects per player" in the host options. Default 100; 0 is no limit - The host and a server's admins are not limited - At the limit a player's game refuses another object, from the native object tool and the park editor, and the menu shows how many they have placed - Enforced by the host or server, which shows everyone no more than the limit of each player's layout; objects already shown keep their place - The limit travels in the roster, which takes the protocol to version 43: builds before this cannot join sessions with builds after it - The protocol tests link again (the server browser needs the identity lists since the official servers change)
