I tried to convey the information althought given object type is vulnerable to fire a particular item may have been protected against it. It specifically says "object type", not object. Will improve that one.
Actually turns out crawl.cfg is fine. The display of object-verb command system was royally screwed. Fixed. Good catch.
You nailed the thing with wrench. Wield criteria takes into account weapons instead of any item that has known melee/ranged/aimed damage. Easy to fix. The wrench has 2-7 damage and chance to stun. Mop has 1-8 pus one from enhancement which makes it 2-9. More raw damage but stun is very useful sometimes. Its a toss up which is better. I usually stay with the mop.
I was doing rather well when suddenly my strength was reduced to 7 and i became overburdened. I tried waiting for it to be resolved but it never went up. I also removed all my items accept the necessities of weapon and armor and could not lose the burdened status. To add to this I apparently got exposed to radiation (strange because I had a geiger counter and it didn't alert me at all). I didn't know what to do so I pretty much died helpless in a corner 
That is the kind of unfortunate thing that I had no idea how to deal with that makes people not play a game again. I really like this game though so I will still play 
Strength dropping is caused by either poisonous melee monster attack, getting zapped by a poison ray gun or drinking poison. Ability damage must be cured with restorative items or powers.
Was your Geiger counter activated? It has to be on to work.
I drew two conclusions. First, strength damage should be outlined numerically and in red color to alert players to what is going on.
Second, radiation symptoms are too subtle. This might warrant a "required" spoiler if left that way, so making them stand out somehow is a good thing. I'll try yellow message color for a start.
Wait, third conclusion. Next spoiler should obligatorily be speaking about radiation in detail.
