Dixon says: "Just try to get the toolkit and get out of there as quickly as
possible. Best of all, it's completely harmless to biologicals"

I think there is a missing sentence in there where Dixon gives me some sort of
explosive. It's the explosive that's harmless to biologicals, not the toolkit.

I got here by telling Dixon I thought the bots were sentient, then telling him I
was joking.

Ok, it's there:
dialogs/Dixon.lua:389
But it doesn't fit the description of your report... Oh wait. You mean that we 
should reword it?

Hmm... Reproduced the bug...
 Dixon should had talked about the explosives. Odd.

Hmm... Funny. Lua doesn't seems to be processing the engine...

Ok, this shall work for now:

Change line 383 in Dixon.lua to:
"			else -- 1 grenade"

This way, it will work.

...Still a bug. I'm going to debug a little...

...a few minutes of debugging, I think that lua is registering the difficulty as 
a local var but when it reaches the 'if' loop, it reads a (inexistent) global 
variable.

I may be wrong, of course.

Good finding! Should be fixed with commit
