problem with .bsr file ( Data\res\char\china\chinaman_monkey )

the problem is when i try to edit the chinaman_monkey.bsr i get crash from the server after i save and import it, so i thinked maybe because the change i did, then i back to the file and i reback the file to original then i save then i import it again, then the same crash


wish means its all about how i save the file i guess, so please help me to know how can i edit and save .bsr files

the edit was

prim\ani\char\china\man\skill_ch_spear_base_b.ban1
to
prim\ani\char\china\man\skill_ch_tbladespear_base_b.ban1


and yes i have this thing on the place and its working perfectly...
