MobMapUpdater v1.61
You should get the new version the next time you start the Updater (in case you're using the automatic mode you'll see a notice about the update the next time you end a WoW session).
[edit] I have stopped the distribution of v1.61 for the moment, as there might be another bug in there. I have to run some tests to determine if there's a problem. If there is one, I'll fix it and release v1.62, if there isn't I'll re-enable the update from v1.60 to v1.61.
[edit2] All right, it was false alarm. v1.61 seems to be fine and stable now.
