I am confused of this CoreScript Error (Is it something wrong with CoreScript?)

Hello there. I am confused of what this CoreScript Error is about.

(I don't have a copy of the error and it doesn't look accurate, but it looks like this):

Infinite yield possible on RobloxReplicatedStorage:WaitForChild("GetServerVersion")

Basically all that i can remember.

This tells me that something is wrong with my game when it showed up.
