Error Vertex File for 'props_pipes\Gutter_256_002a.mdl' checksum 1190297085 should be 1190308605

I have no idea what is happening but this error gets spammed into the console every 10 seconds. The server disconnects as well for like 2 seconds. If anyone could tell me what is causing this, I would be grateful.

I’ve encountered that when using CS:GO props in CS:S

Corrupt file or invalid format? Checksum is one of several types of error-checking that could be done between client and server.
