well hi i got a server i have some custom maps on it
i tryed to add 3 new maps

dod_tiger_source
dod_sherman_b7
dod_chuchyard_b5

and when im trying to load the maps it says

CModelLoader::Map_IsValid: 'dod_tiger_source' is not a valid BSP file

same thing with all 3 maps
any idea y is that ?

btw server runs on linux and all files were opened from a zip file
