When I set up a test server on my own computer using the Steam client and type c_give() to give a prefab that can't be stored in the inventory, the game starts to lag. The first few times the server eventually crashed and the save files were corrupted. I tried it again now. It lagged again, but server didn't crash. I reconnected and it still lagged. I shut it down with c_shutdown() and restarted. This was in the log:
[00:00:06]: [string "scripts/saveindex.lua"]:264: Corrupt Save file [session/73B631138D620AE0/0000000006]
It's not that big of a deal because c_give() isn't supposed to be used with placeable prefabs, but I've been able to spawn pig houses and rabbit houses that way when hosting a game.

Connect to a dedicated server and type c_give("pighouse").
