And it never ends. I’m an admin, so I can’t see who spawns what props, previous chats, ect. Can anyone help?

First of all make sure everything is working fine.
And if it keeps happening,and everything else is fine.
Then this goes into console:

developer 1
con_filter_enable 1
con_filter_text_out “gamename”

What this does it hides the text from your console log.
