Here's the NavMesh that it's giving me for Eastern Thanalan (This is near the lv45 Mining deposits). Didn't look like this a bit ago, but after it updated this is what it shows. I have tried updating again and it's still the same. It's getting really messed up trying to mine here.
EDIT: Not letting me attach the SS for some reason. Here's a link to it.
