So I was testing my map with a friend and we got and error saying this

This never happened to me before.

Have you seen this?

I don't know which configstring error means which, but I've gotten multiple ones and the things I thought it would have been when I got this error only with multiple players were:
 - I had too many shaders precached, I started using menu instead for hud icons, except for full screens
 - Using playsoundatposition too much
 - I kept setting the text of a hud too often or to many at the same time.
