Okay, in the western chamber there's a set of steps down to another catacomb. Thing is I went down them, and then thought I'd better save in a save place first, so I popped up the stairs, saved and now I can't get back down the stairs, it doesn't even register as anything under my cursor. What gives?

thats the eater-egg aerea of the KAA GENT scroll, nothing important. btw it is a Belgium soccor team.
heres a screenie of the scroll

Hi DrDerekDoctors,

As joliekiller says, there's nothing important over there. You can only enter through that tile one time, the second time; the access through that tile is gone. This is not a bug, it's meant to be like this. This was invented by one of our story designers, who is a huge fan of that Belgian soccer team, that's why you could find the scroll with the Indian (=symbol of that team). So: nothing important <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> (I'm not a supporter of that soccer team <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />)

Oh, righty. Well that's okay then. I thought I'd broken the game again (first time was the cemetary/garden key mix-up). <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />

Back to Orc-smacking then. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />

I did that, too. As well as opening the crypts where you sacrifice the Hoyl items, thus ruining that quest, too. D'oh! <img src="/ubbthreads/images/graemlins/ouch.gif" alt="" />

FIX for broken Holy Items quest
