Using version 15 & CEP
Tried it with no other mods active, including CSD which I take it prompted the change.

I didn't do anything I swear! (I cannot back this statement up with evidence)
Did you delete the cityview.lua file out of CSD's directory? Not doing that alone will cause problems with EUI.
Also, sorry you are getting flak from people for your excellent work, bc1. Some people just don't understand how much time goes into the work we do. We have no resources, no beta testers (well, we have them, we just call them 'subscribers'), no dev team, yet people expect speedy magic perfection. Blurgh.
I've received hundreds of rather unhappy messages over the years from people. You just have to ignore them.
