Can someone state the problem in a succinct form, so I can insert it into the "actual errors in the packet" list?

Ouch! That's harsh...especially since chalk isn't flammable.

Almost any powder is flammable when finely dispersed, I thought? Roll chemistry checks everyone!

Hmm, the problem is that 'Heavily Obscured' is described only as a means to hide, but it's not clear what the effects are otherwise. It's also not clear what effects obscuration has on the vision of those inside fogs, heavy rain etc.

There are two kinds of chalk - one of them burns explosively, the other is inert.

At least that's how it is in Swedish. We call them quenched and and unquenched chalk. I discovered that burnt chalk is called quicklime in English. That burns magnificently. We mine quicklime in Sweden under the name chalk (all translated, of course). Regular chalk not so much.

So much for thinking related words mean the same in two languages.

Pretty much. Not technically "anything", but a lot of things that you wouldn't think are combustible become so if in a fine enough powder dispersed in air. Grain silo explosions come to mind.

Invisibility makes you heavily obscured, if your are heavily obscured anyone can attack/target you, just at disadvantage (but you have advantage to attack them), but if you are heavily obscured you can take an action to hide (if successful then they can't target you).

So I have to make a roll to just stand still and not make any noise? Ah, the quirky rules of D&D strike again!

There are four necessary conditions for a dust explosion or deflagration:

A combustible dust
The dust is suspended in the air at a high concentration
There is an oxidant (typically atmospheric oxygen)
There is an ignition source[1]

Many materials which are commonly known to oxidise can generate a dust explosion, such as coal, sawdust, and magnesium. However, many otherwise mundane materials can also lead to a dangerous dust cloud such as grain, flour, sugar, powdered milk and pollen . Many powdered metals (such as aluminium and titanium) can form explosive suspensions in air.
