[1.2.3]Wraithform not working

[Parcae2]

When I try to move into a wall, either by clicking or by using the movement keys, nothing happens.

Edit: When I moused over the effect description, it says no natural obstacles, so that's probably it.

This seems like a pointless restriction for what's already not a terribly strong talent. At the very least, it should be in the talent description.
