There seems to be a bug with assess teaching.

I got this today when assessing teaching in a room.

assess teach
You assess the teaching environment...

*** is teaching a class on extremely simplistic (compared to what you already know) Stealing which is still open to new students.
Roundtime: 5 seconds.


exp stealing
SKILL: Rank/Percent towards next rank/Amount learning/Mindstate fraction
Stealing: 0 00.00% clear (0/34)


>>

Seems that the comparison breaks in some way. Since the person teaching had hundreds of more stealing ranks.
