Many thanks to those who responded : )
Here is a brief summary:
No-one has found anything seriously wrong - such as falling through floors or walls, thank goodness!
I have packaged the Age as both zip and rar files now.
It's probably not going to work with multiple players because if someone turns the power off, anyone "upstairs" won't be able to get back through the first gate.
When walking through water, sometimes your ripply wake disappears and I think that has to do with how the camera follows when you change direction.
Also when walking through water you don't get the swashy sound effects and that's because I couldn't find how to apply them - they're not in the foot sounds list in the Max plasma plug in. Any ideas?
Oh yes, the ladder is wobbly!
That's it, it's finished!
So here are the links
rar archivehttps://www.dropbox.com/s/i6usx8qj6bo99 ... 1.rar?dl=0
zip filehttps://www.dropbox.com/s/11gg2fq41olfb ... 2.zip?dl=0
Unpack the archive with WinRar or WinZip and copy the extracted files into an existing Uru offline installation. Link to Terahgrahm by using the command /link Terahgrahm or from the book in Relto or the Nexus.
