There is a new zone that has a wormhole selection available that isn't added yet.

Tried to added it myself but didn't seem to work (maybe since it's own it's own map?)

This is what I had though:
data[109715] = { -- "Flip the portal horizontally and dive into it."
mapID = 2133,
x = 0.85,
y = 0.8,
tooltipMap = 2133,
}

Edit, ah it put it on the map for the new zone.

I thought I pushed an update for this but because of the GitHub outage today it must have failed.
