No need to go to source edit for your problem....
Go to ur item_db.txt (pre or renewal depending on what you're using) and change this part
 
4077,Phen_Card,Phen Card,6,20,,10,,,,,,,,136,,,,,{ bonus bNoCastCancel,0; bonus bCastrate,25; },{},{}
into
4077,Phen_Card,Phen Card,6,20,,10,,,,,,,,136,,,,,{ bonus bNoCastCancel2,0; bonus bCastrate,25; },{},{}
 
answer is from rathena/doc/item_bonus.txt where
 
bonus bNoCastCancel,n;                          Prevents casting from being interrupted when hit (does not work in GvG | n is meaningless) bonus bNoCastCancel2,n;                        Prevents casting from being interrupted when hit (works even in GvG | n is meaningless)  
HOPE it WORks !!

you closed the server manager(char/login/map .exes) b4 logging out??? thats why some servers(online) always  remind their players to log out b4 server shutdown/maintenance to prevent rollbacks (if there will be any)
