Hacker can access computer through walls

[srmalloy]

I'm not sure that there's going to be any way to fix this, but the 'take NPC to target' mission goal appears to work purely on a proximity basis, with no regard for map geometry. In the "Rescue Hacker from Tsoo" mission given by Thao Ku, the computer you have to take the hacker to is in the corner of a room that is folded back on itself (I'm sure players will recognize the map):

The quirk is that you only have to bring the hacker to the base of the stairs, which makes him close enough to the computer for the mission complete to trigger, even though there's a solid wall between him and the computer, and you would realistically have to take him through the four stairs to get to the end room so he could use the computer.

 

I've seen the same thing happen when the end room is similar to this one, but has the elevated half-floor with cubicles underneath; all you have to do is pull the hacker under the computer for the mission to complete. Adding a line-of-sight check to the proximity check might work, but I don't know if that's feasible to add.
