I have had the latest patch 1.9 since its release and this command was working 2 days ago. When I started playing again today it presented the above error. So I did a cache verification to make sure nothing was wrong; 1 file was fixed.
Below is an example of what I've actually typed on a brand new character generated without any mods installed subsequent to verifying my cache:
incpcs destruction 1
The error still occurs.
Did patch 1.9 turn off this console command when it modified "fixed" the Oghma Infinium glitch?
Regards,
Bram
