Spells: Harvest Resetting When Porting

[ymw]

As nice as it is, pretty sure this is unintentional. Often when porting shortly after casting Harvest, the icon is refreshed when I land at my destination. I haven't noticed this reliably with any given port, group or solo, but it seems to happen about half of the time.

I'll test this with normal zoning, but if that works, it may be a slightly more important one to fix, as that's a bit more exploitable.
