Bug: immune_casting checks wrong variable when missing a character.
Danger: Medium - NULL string access, bug message
Found by: Zeno
Fixed by: Zeno

---

magic.c, immune_casting

Locate:
      else if( skill->miss_char && skill->miss_char[0] != '\0' )
         act( chit, skill->hit_char, ch, obj, victim, TO_CHAR );


Replace with:

      else if( skill->miss_char && skill->miss_char[0] != '\0' )
         act( chit, skill->miss_char, ch, obj, victim, TO_CHAR );


This code is used again a bit further down in the function and needs to be fixed there too.

Because this part of the function is checking the wrong pointer, it can lead to string comparison log messages, and possible crashes due to a NULL string access. Obviously if it's checking miss_char, it should display the miss_char message.
