But I didn't even sub the stormfox addon before , I only add it to favorite so I can find it later .

You* might have an addons which changes your game render such as "Extender Render Addon"

So that's the addon that cause the light issue?
I'll give it a try disable it and see if it works.

But the elevator button thing , is that only on my end or thats a bug ? after the experiment gone wrong , I can't use the elevator to get out :\
