The error dump.

[amaprotu]

I really don't know what would be usefull to you, George, but it seems to me there are a couple of pieces of information that could be included in the error dump such as x,y,z position in the dungeon and the name of the dungeon file being played. Maybe also the names of the characters.
Those just seem to be questions still asked when someone posts their error log.

I could be maybe useful also, to include the last action performed and the last object used.

As it happens, the x,y,z (and direction facing) co-ordinates are already included in the dump if they are relevant to the situation.

The dungeon name could be useful however...thankyou!

Done in V0.25ish!
