Checksum Error?

[Magicswap]

So when I download the megapack and join a server not related to TNB I see console spam about certain character models in servers and the problem models appear invisable.
Here is a console sample: Error Vertex File for 'Humans\Group03\male_02.mdl' checksum -1451030114 should be -77034264
If anyone know a fix for this that would be nice.
