[Derision]

There are no invisble walls in airplane that I can see when viewing the zone in OpenEQ.

My guess is that it is something to do with the 'Underworld' field in the newzone struct, e.g. when you try and walk off the edge of an island, the client detects there is no 'floor' underneath where you are trying to go and so stops you walking off the edge.

I changed the Underworld column in the zone table for airplane from -2030 (something like that) to -5000 and it let me fall off the island you land on if you #zone airplane. Give that a try and see if it works for you.

If you can get a collect with EQExtractor2, it would be interesting to see what the correct value for Underworld should be.

EDIT: I noticed when jumping off islands that more often than not it would zone me back into airplane, when I thought it was meant to zone you into freeport ? (I've never messed around in that zone so not sure, but that is what I have read). Maybe something else needs tweaking as well. (Was testing with SoD).
