1.6.5 Guise of the Hated/Creeping Darkness bug

[GlassGo]

When character wearing Guise of the Hated that grant him Dark Vision, when Creeping Darkness procs, you can't teleport inside it like if you have no Dark Vision.
Also, aiming is happening in a way like if you have no Dark Vision - only in straignt line.
Very unconvenient.

Hum any other thing that could be interacting? I can't reproduce it on a simple scenario

I have also noticed that in some cases the dark vision provided by guise just wont seem to work. I'm wondering if darkness effects are being applied in two different ways by two different effects. Dark vision works for one of these, but not for the other. (this might be entirely intentional though)

Any other thing is being mind-power based class I guess.
Teleport I tried was Dream Walk.

[GlassGo]

Up.
Happens in every fight.

...And died in prides, probably if I could Dream Walk in Creeping Darkness I could survive. Or nor, but there was a chance.
