I got stuck in a crack in the geography, don't know if this is something you'll bother fixing but it did get me killed, which is always annoying. Look at the picture here
I fell into this crack, and then there was no way to get out of it even though I wasn't even standing to my waist. Jumping in all directions was to no avail, I couldn't sit to do /stuck, and when mobs on the picture went for me I couldn't calm them because I was told I must be standing still to cast nanos. Visually I was standing still though, and I certainly wasn't doing anything to move when trying to cast. As this is a new bit of geography I post this here as a bugreport.
