Ok Now everything is happening twice.
-Chat message events.
-item Spawns events.
-Player camera
why is it all happening twice?
I don't know why it happend with the chat message and item spawns events, but for the camera events I have an Idea.
It happend with me too. If you have two bricks called "brick" and you use a camera event on the name:
onactivate_named brick_brick_set player camera_free
Then It will say twice that your in camera mode, but actually your not in camera mode, your in the admin ball thing.
It's a glitch, bug or how you call it.
Sorry if it didn't helped. THis is all I know.
