So, after 2 rl days of cave exploring I finally found a Demonic Fortress. Excited I rushed inside... just to find out it was empty. Completely devoid of (un-)life. A bug? Maybe, but I bet hell itself is FULL of demons. So after grabbing the adamantine sword and rushing down level by level of the fortess' basement I begin to wonder why it is so empty down there.. shouldnt I be swarmed by hordes of demons?
And then I found one: A water demon. My sword held high I rushed towards it, just to learn that water demons explode on the slightest contact with anything solid. Odd. A few levels further down I encountered a second one which sprayed me with its dust. I killed it, licked the dusting from my armor and climbed further and further down, waiting for a syndrom to kick in... After another dozen levels I thought to myself "Well, maybe it didnt really ZOMGWTFBBQ WHY AM I CONSTANTLY VOMITING AND WHY AM I BLIND?!"
Well, leaving a river of vomit behind me i crawled blindly down stair by stair, level by level, occasionally finding a lonely Crundle, Draltha or Elkbird. In hell. Weird...
At some point my adventurer stopped vomiting, but my eyesight is still lost. Oddly my eyes are undamaged and only cease to function.

After 5 hours (!!!) of going down level by level this "limbo" between the Demonic Fortress and hell suddenly stops. No exit, no staircase leading down. Just another empty level, devoid of all life, just like the hundreds I already crossed.
Im seriously upset now! Days of searching for hell and now THIS? My god, this is SO dissappointing. I saw hell from a few missing walls hundreds of levels above, but it was always just a look into the endless red glowing void, never could i reach the floor of hell from these gaps.

What should I do now? Is there a tool with which i can edit a few stairs to the lowest level? Or atleast teleport me over the gaps mentioned above?
Btw: I got the messages for finding the fortress, taking the sword and taking a first glimpse at hell, but never the message of demons spawning.
