some graal prblem ive been having forever.......

[slp]

ill go in a level right and ill see a person it doesnt move or nothin and like lets say stefan was the person he could talk and thats all if he were to attack me it would be like i was getting attacked bye nothing.

also ill be in a quest and somone will be there, he wont move or talk then ill reconect and he's gone.... or somwere else on the level like but i would attack him/her and him/her would just sit there and not get hurt.

whats wronge ?? is it a lag or somthin?
