In related news, several people have said that they've fallen through the world zoning into the Nexus from PoK.
I've changed the random loc code to call the DB so we can disable it, or change the value per zone. I believe this will fix nexus (although, we know small races have general issues falling through the world.) I am also hoping this fixes sebilis (no way to know for sure, I only crash on TAKP), although for that there is something else happening. Even with my code completely reverted, sebilis seems to move the player before they are fully in the zone. Plus, the place in the code the client crashes has nothing to do with location. It's very strange. It'll be in the next patch if it isn't hotfixed in.
