Bug: The AFK flag check in interp.c doesn't verify if the user is a player.
Danger: low
Found by: gatewaysysop
Fixed by: Samson and gatewaysysop

[interp.c]

Find:

	/*
  * Turn off afk bit when any command performed.
  */
	if ( xIS_SET ( ch->act, PLR_AFK)  && (str_cmp(command, "AFK";)))
	{
     xREMOVE_BIT( ch->act, PLR_AFK );
/*
          act( AT_GREY, "$n is no longer afk.", ch, NULL, NULL, TO_ROOM );
*/
          act( AT_GREY, "$n is no longer afk.", ch, NULL, NULL, TO_CANSEE );
	}


Change it to:

	/*
  * Turn off afk bit when any command performed.
  */
	if ( !IS_NPC(ch) && xIS_SET ( ch->act, PLR_AFK)  && (str_cmp(command, "AFK";)))
	{
     xREMOVE_BIT( ch->act, PLR_AFK );
/*
          act( AT_GREY, "$n is no longer afk.", ch, NULL, NULL, TO_ROOM );
*/
          act( AT_GREY, "$n is no longer afk.", ch, NULL, NULL, TO_CANSEE );
	}


The reason for the extra IS_NPC check is because the PLR_* and ACT_* flag sets share the same ch->act pointer and the PLR_AFK check could potentially be triggered in error by a mob with the right ACT_* flag set.
