Passwall fails on herald consistently in desert maps

[AW O'Reilly]

Situation
Herald of storms - undying - desert maps that require lev / passwall - cloud set on the ground or just cleared - mobs recently killed. Herald is wearing passwall and has rested with it on.

Observation
Herald moves while clouds are still down or recently !cancel aoe. Herald dies, "your lungs fill with sand as you sink below the surface"

Herald rez'd, walks around normally w/out dying

This happens repeatedly. Several times during desert run and on different servers on different days. Outkast can confirm.

I can confirm, this has been a bug for years. This is also an issue with paragon innate lev. The difficulty is that, as AW O'Reilly pioints out, this is intermittent. With innate lev I can walk through, attack etc, normally. Then, after standing/massing beyond some point (usually on map 2), this triggers and walking after massing results in "your lungs fill with sand as you sink below the surface" death. I can avoid this by equipping my lev ring for a few secs after standing/massing, as I take the first steps. The lev ring always works fine.
