invocation vs being trapped

invocation vs being trapped

     I can't find the report about this; I must have deleted it after
reading, or else recently reread something so old that I'm not going back
far enough now.  When you perform the invocation ritual to create the
stairs down to Moloch's Sanctum, any trap at your location gets deleted.
But if you were in a trapped state at the time then you got left in that
state.  Descending stairs doesn't check for traps so you wouldn't notice
unless you tried to move around on the same level first.  Then you'd get
"you're stuck in a pit/beartrap/web" even though it wasn't there anymore.
