Error Vertex File

This error is spamming my console when my client tries to draw my playermodel, the trigger seems random but idk.

Error Vertex File for 'breen.mdl' checksum -392848939 should be -147354707

I tried verifying integrity for both my client and my server, it happens for basically all the models in the “models/humans” folder.
Does anyone know why this error occurs or what to do about it?

If you have player models skins - remove them. If you have addons that override default player models - remove them.

Turns out I did override the player models in an addon, removing those and a restart fixed the problem, thanks!
