[Question] WMO fall through

[Someonecool]

I edited a ramp in an arbitrary instance.
I made it go outside the normal WMO - but once I venture up it, I fall through it. This happened when I would have gone outside the original wall. I changed all flags and tried all the # the original had - that didn't help.

Anyone with some input?
