I know this buff type is for the Random Events, but has anyone ever successfully used it outside of that?  So far all it does is dump the game if you try it with any "Apply Buff to Target..." or "Apply Buff To Self"

I assumed, from looking at the random event file, that it temporarily changes your player index to neutral, while it spawns ships at a random planet.  So when those ships spawn they are neutral instead of on your team. Then once the spawning is done, the buff ends and your player index is back to normal.... Either that or I have no idea how it works haha.
