Mage casts Fireball at a ganger and they survive, but gain the Burning X status. When, exactly, do they start to take damage from the status (after attempting to soak, of course)?

1. Does it happen on the ganger's turn, the mage's turn, or the end of the round? (EDIT - Ignore this part. I'm stupid. It says end of the round right on the damn page... *sigh* - 2nd question still applies though)

2. Do they have to start soaking damage during the current round or does it wait until the following round to start affecting them?

The answers to your question are left to the table GM to adjudicate on a case by case basis.

Personally, I'd probably have the damage "tic" during the burning character's turn.

Do several status add up? (Burning 2 + Burning 1 = Burning 3)
Or only count the highest?

[Stainless Steel Devil Rat]

Well statuses stack.  So if you have Burning 1, and suffer Burning 2, you now have Burning 3.

So, in effect, you add them.

Where does it say statuses stack?  Do you mean in as much as you can be both chilled and wet?  Having more than one status is totally different than stacking status.  There's no mention I'm aware of about what happens when someone with burning 2 receives another burning 2.  I think this is up to the individual table.

Well, in the case of something like Invisible #,  it makes sense to say you can't just cast a whole bunch of Invisibility spells and be REALLY invisible...

But others are more common sense. You have Fatigued 1, and you got MORE exerted? You don't have 2 separate instances of Fatigued 1.  The nature of fire, to me, implies that when something is on fire, and you make it MORE on fire, it's a more dangerous burn rather than being on fire twice.

[MercilessMing]

Burning in particular gets really nasty if you do it that way, cause every fire elemental does its force in damage on the attack and then its force in damage again at the end of the round.  Doubling that DoT would just get crazy.  And we all know spirits don't need buffs  
In other games, I think it would be the nature of damage over time abilities to reapply the DoT as opposed to doubling it. 
In your example, making something MORE on fire, you're hitting it with a damage + DoT ability.  The extra dangerous burn can be represented by the initial hit.

in 5E, under the heading "Fire Damage" you find this info:

...When something catches fire, the fire has an initial
Damage Value of 3. This damage is caused at the end of
each Combat Turn, and the DV increases by 1 at the start
of each subsequent Combat Turn until the item is completely
destroyed or the fire is put out. You can fight the
fire a number of ways (water, smothering, etc.), making
an Agility + Intuition Test and reducing the fire’s DV by
1 for each hit. Remember, as long as the fire is burning
it can ignite any nearby flammables, including furniture,
vehicles, foliage, and elves....

Now, I have been much to busy recently to even buy 6E... But check under "fire damage" to see if they say something similar. If not, then maybe they forgot that part... (Or changed it?)

Fire doesn't get worse in SR6:

Burning #
The Burning status is the result of being hit with
a flame-based attack. Once the initial blow has
done its damage, you have to deal with the continuing
heat and flames, and the parts of yourself
that may be on fire.
The status should be noted with a number that
indicates the amount of Physical damage the character
must resist each round while the status exists.
There are multiple ways to remove this status.
You can spend a Major Action and roll an Agility
+ Reaction (2) test; success means the fire is out
and the status is removed. You can also jump into
water to remove the status without a roll.
If you gain the Wet and/or Chilled statuses,
the Burning status is canceled. Similarly,
gaining the Burning status cancels the Wet or
Chilled status.

Also:

Gamemaster note: The damage and duration
are subject to your discretion if the target has
some mitigating circumstance. If they’re covered
in oil or wearing a lot of loose-fitting cloth, it
may last longer, cause more damage, or require
a higher threshold to extinguish.

So there's no explicit stating the two Burnings would stack, but the GM can rule so depending on the circumstances.
