(20b) level 5 of Trollmire still inaccessible

[martinuzz]

I remember reading a report about this a few days ago, but I can't see it in the list anymore.
But it is not fixed:
Upon entering level 5 of the trollmire, I have no way to explore the level, except to go back and scourge the levels above for a pickaxe.

This is the layout that traps me:

Code: Select all

TTT   T=tree
..T   .=grass
<TT   <=stairs
TT

EDIT: oh. duh. sorry. I just realized that I'm posting this in the wrong bug section. I'll make a reply/post there, feel free to lock/remove this one.
