Particles appearing in 3D skybox when it's not supposed to.

[Linxy]

I'm working on a halloween version of badlands (koth) for me and a friend, and I added the hammer_souls_rising particle about 460 units above the capture point, but for some reason they also appear off in the distance where the 3D skybox is placed outside the map. I tried raising the skybox in the regular area of the map, thinking that it was because the particles were going up beyond the skybox, but that did nothing.
Is there any way around this?

UPDATE: after another look the particles in the 3D skybox don't actually appear where the 3D skybox itself is placed, but on the opposite side, but still outside the regular skybox of the main play area.
