I'm running a dedicated CS:GO server on my PC, and after ~5 mins of running the server, a hundred or so lines like this spam through console.

Pure server: file: GAME\materials\paintball\pb_yellow.vtf ( 1 22416 5640 ) could not open file to hash : ab7e566d6367c6477d0a1274ac97129f :

I'm just curious what these mean, what causes them, whether or not they're a problem, and how to get rid of them.
