I found the problem. The thing was that in the DirectorBP of a particular sequence I moved the vrorigin of the vrpawn to a specific place in the world instead of moving the whole actor. So, doing it that way was leaving the Capsule Component, which is the root, down at the landscape and moving the rest of the vrpawn to a particular place in the sky. So, when I tried to move the pawn down, the capsule was colliding with the landscape. I found out by setting the capsule hidden option to false. I guess that I moved the vrorigin instead of the whole actor because I was having trouble doing it the other way. But, I managed to do it the right way. A rookie mistake!
