Digging pits in D:49
Inconsistent behaviour when digging downwards in the ice level
Something I recently remembered: Years ago, the very first time I got to D:49 (the frictionless ice level), I tried to solve it by digging the ice on the ground away with a pickaxe. Well, TB apparently had never thought of that: What resulted was just a pit, but more importantly, I couldn't climb out of it by the usual means (walking in some direction). The game claimed that I would slip and fall. It's also impossible to throw anything while in a pit, so I couldn't move my character that way either. I thought that I had ruined my game by becoming permanently stuck! Luckily I discovered that 'a'pplying the climbing skill allowed me to escape.
But why would one method of climbing out of a pit work but not the other? The game apparently thinks that any attempted movement is on the ice and thus automatically fails, overriding situation-specific interpretations like climbing out of a pit.
The game should either
1) make it impossible to dig the ground on D:49
2) make movement attempts inside pits on D:49 behave the same as anywhere else
3) allow digging the ice away as an alternate solution, making walkable ground tiles.
