Weird Exit Text

I wanted to make it so certain races can't be certain classes, so I followed the instructions on Darkoth's site, which were basically to add the check

if (pc_race_table[ch->race].class_mult[iClass] == 0)
continue;

into the void nanny function of comm.c.

I did this, and it had the desired result of letting me exclude classes for a race by setting that class multiplier to 0.

However, my exits now look like this:

A Room in Mud School
You are in a square white room. The walls are all blank, with no windows.
Light fluoresces off the ceiling in soft white tones. Of course, there is a
sign on the wall. The exits are west and south. A small plaque is on the
wall.

[Exits: Exsouth/Ex Exwest/Ex]
(White Aura) An acolyte of Zump welcomes you to mud school.

I don't see why it would cause this, but I went back and restored the original comm.c, and it worked normally. Can someone help me out here?

Something in nanny shouldn't really affect the way exits are displayed. What else did you add?

I'm pretty sure that I never changed anything else, since this was all I was working on today... couldn't find it though, so I just restored the old file and redid the change, and it works now. I must have slipped and typoed something somewhere else and not noticed. Sorry about that!
