[1.3.3069] Ideology terror bug / feature ?

[vevi33]

I play on the latest vanilla version  and the terror system simply doesn't work properly. I often experience that the slaves have 0% terror even if they are in a room with many skullspikes / cages / terror sculptures (while they are awake, not sleeping).
Can anyone explain this?
I know the terror always 0 while they are sleeping. And I also have slave collar on the mentioned slave.
Thanks for the answers.^^

Moderator Note:
Your slave is too far away from your statues, they all have fairly short radiuses, about 4-5 tiles. You need to spread them out more or have the slaves working in smaller rooms.  thanks for the report!
