These may have been answered already, so sorry up front if I missed it.

When does the counter on vanguard currency reset? I think the max you can earn in a day is 100, which I did yesterday.

Tuesdays, around 5am EST. It's 100 Marks per week.

When I start a new game, all my heavy weapon ammo is gone, no matter how much I had before I logged out of the game. Is this a bug or a 'feature'?

Feature, you could say. It's an intended consequence of new matches.

Where did the creepy dude in the tower who takes the strange coins go? I found home once when I couldn't afford anything from him. Now I've got the coins and can't find him.

Xûr. He only shows up Friday and Saturday. He moves to random locations, but this week, he's down in the hangar, by the shop that sells Cabal weapons.

I only got credit for 1 walker kill even though I was part of an impromptu team that took down three (daily challenge). Anyone else have that problem?

I had that problem. Were you dead when one was killed? Might be the issue.

Any news about the soundtrack release date?

Lets ask Marty... Oh wait...

Thanks in advance

Poop. :3

It's actually 100 a week, it resets on Tuesdays at 2AM PT

Not sure about this one. I usually finish my night with a few Crucible matches, so my heavy ammo is always gone when I log back in.

He's in a different place every week. This time he is in the lounge under FWC that you get to through the shipyard.

From my experience unless you are in an actual fireteam you only get credit if you get the last shot. In a fireteam you all get it.

Sadly no.

Thanks in advance

For the Queen's Wrath Bounty? Killing blow counts. 'Assists' don't count. But 'Proximity Assists' DO count. i.e. stand near whoever else is shooting the Walker and you should all get credit.

Where did hear this? I forget :/

Any news about the soundtrack release date?

It released today!! See here.

(I would post a link to my recent post in relation to the BWU, but I can't seem to figure out how to link an internal post...?)
