StringPool.GetNumber - no number for string fx/weapons/vm_rock/strike

I'm not sure if its an error but in my console its coming out non stop for like 5mins and then stop.. then it starts again.. and it goes over and over so..

This is the message that console gives to me
StringPool.GetNumber - no number for string fx/weapons/vm_rock/strike

 

Make sure everything is up to date as the client and server both were updated. An Oxide snapshot for the latest update is currently not yet available though.
