Do you have any custom mapping? If so, are you also using a streamer plugin with the gamemode/server?
If that's true, check your code and make sure any functions similar to...

pawn Code:

CreateObject(...);

Is changed to what the streamer requires.
Eg. Incognito's streamer requires all CreateObject functions to be CreateDynamicObjects.
This is the same for movement, removal and/or other object that can be wrote into the game.
