Steps to reproduce:
1. Start two instances, editor - "Server-Only", build - "Client".
2. Connect the client to the server.
3. Click "Start Game". This will NetworkServer.Spawn() the object from the pool.
4. Click "End Game", which will NetworkServer.Unspawn() the object, returning it to the pool.
5. Stop the server.
6. On the instance that was previously the client, start a "Server-Only" game.
7. On the instance that was previously the server, connect it to the new server.
8. Click "Start Game" on the server.

- Game freezes

Expected: either it stops from activating this object and throws an error or works without flaws
