Due to changing zones by mount while fiddling around with the guide list, the following error occured on client restart:

The uid in cache appears to be nil, so it wrecks the whole addon with the following call in WoW_ProMapping:
TomTom:RemoveWaypoint(cache[i].uid)
a check on nil did the trick for me so far:
if not cache[i].uid == nil then
TomTom:RemoveWaypoint(cache[i].uid)
end
I still get a "Zone not found. Using current zone".

Edit: Ok, I found the reason. Blizz changed the zone name for Howling Fjord in the german client: "Der heulende Fjord" -> "Der Heulende Fjord", so it's actually a Lib-Babble-Zone-3.0 issue afiak

I grabbed the most recent version of Lib Babble Zones. Let me know if it's still a problem!

Whew, okay. I'll manually edit that for now and watch to see if Lib Babble Zones gets an update. Thanks very much for the detailed feedback, very helpful! :)
