Adjust Rescuee pathing check interval

[srmalloy]

It's an annoyance, rather than an actual bug, but can the interval at which rescuees check for pathing updates be decreased? If you have a character that's flying, and you defeat the mobs threatening an NPC -- like the possessed scientists in the plaza of Portal Corps -- the rescued hostage will usually go running off in some random direction where they can find a way to increase their elevation (i.e., the hills around Portal Corps, a fire escape, etc.) to get close to you to reward you with inf, and even if you fly right up next to them, they'll usually keep running toward whatever point the server has picked for them, completely ignoring the fact that you're right there next to them. If the interval at which these NPCs are checked to update their pathing to your current location was decreased, this would reduce some of the 'runaway rescuee' cases.
