NPC Activation doesn't work properly

NPC activation is currently very tricky. You need to find the right spot and probably the right angle too. Some NPCs are almost not activatable.

This issue is tagged as major and urgent, because it makes all further development regarding NPC interaction very annoying and unnecessary time consuming.
