Heal companions error?

I've heard from at least one person about a bug that can supposedly crash the game when you are trying to heal companions.

Last night, I tried my darnedest to crash the test server by healing my companions... but wasn't able to do so. I am healing them by typing their number (single digit, 1-4) and pressing LAB (F7 or ctrl-l).

If anyone out there knows how the heal companions event can cause an error, please let me know and I will fix it.

Thanks!
