Here's the code:

define room <Outside Grate>
look <You are in a 20-foot depression floored with bare dirt. Set into the dirt is a strong steel grate mounted in concrete. A dry streambed leads into the depression.>
north <At Slit In Streambed>
south <In Forest 1>
east {
set numeric <rnd; $rand(1;2)$>
if ( %rnd% = 1 ) then goto <In Forest 2> else goto <In Forest 1>
}
west {
set numeric <rnd; $rand(1;2)$>
if ( %rnd% = 1 ) then goto <In Forest 2> else goto <In Forest 1>
}
southeast <Below the Grate>
place <Below the Grate>
script if property <Grate; open> then displaytext <describe Grate open> else {if not property <Grate; locked> then displaytext <describe Grate unlocked>}

Again, the q3extension is in there.

Any thoughts?

I also get odd text in the game when 'taking' a simple object. E.g. the following object:

define object <brass lantern>
alt <lamp; light; brass; lantern>
take
prefix <a>
end define

when i select the object in the objects window and click Take, it says:

> take brass lantern
(assuming you meant to take the lantern).
You pick it up.

If I type Take brass lantern I get the same, but if I type Take lamp (or any other variation) I just get:

take brass
You pick it up.
