Using Version 80100.10-Release

Clicking a destination for the Mole Machine only closes the map and takes me nowhere.
This is the Error message wow provides

Please try that change before I push out a new release, just in case there are any other issues I've missed (I don't have a DIDwarf so I can't test myself).

Found a (slightly hacky) solution:

f3510e9

The reason we had an invalid NPC was because we closed the gossip prematurely, the delay fixes that.

Gonna give it a go when I'm back at my pc, thanks for the help!

Tried it, still same result, just looks like this when I try using it, no error message pops up at all now

Should probably clarify that it is working for me with all the other modes of travel without error, only the mole machine isn't working, and it gives me the same issue with InteractiveWormholes being the only addon enabled

I see the issue now, I'll get a fix out shortly.

Seems there is still some weird issue with this.

So, the issue I'm seeing (this is very technical, but I'm dumping this info regardless) is when I "hide" the default gossip window (by unregistering the event that would normally show it) I lose track of the NPC it exists for, so when the second gossip window shows, it has no NPC correlated with it, thus none of the zones gets clicked (and this is why you'd see the gossip window when you click the zone).

@Bexan Did you end up testing it?

Sorry, dissapeared from wow for a bit. Back now and tried the changes to addon.lua and the molemachine module but still getting the same issue, it closes out without sending me anywhere.
The only difference I found now is that if I interact with the mole machine quickly again after attempting to go somewhere, it'll just open the normal in game map, without any clickable wormhole icons : / Closing the map and interacting with the wormhole again gets me the map with the interactable icons, but still no functionality.
