My unit model isn't appearing!

[FrozenShadow]

When I upgrade my unit, a tower, from "Scratcher" (Zealot Model) -> "Ravager" (Dark Zealot Model) it upgrades the damage is refreshed, everything works as it's supposed to. But, the problem is, for some reason the model of the "Ravager" stays as the Zealot Model. If I pre-place the tower onto the map, it shows the proper model, it only happens when I upgrade it in game. Any ideas? I've tried looking for the source of the problem, yet I've come up with nothing. :banghead:

I'm done, I've fixed it, it was something with the actor's events.
