I personally believe I received the prizes for placing top 3, but wasn't given any of the bonuses (Other member winning, multiple crewmembers in top 3).

I can only speak for myself, and I'm totally open to the possibility that I'm wrong, but I believe I only received gifts/personals for the individual placements I had as twigs. Looking at my gifts page and comparing to the dice event in January, I received these kinds of gifts in both events:

From Dice Winning Streak

From Dice Losing Streak

In addition, the January event also generated these gifts the following gift, which the August one did not:

From An Upper Placed In The Dice Event

This, along with the fact that I did not receive any personals about gifts due to Daiquiri or Void (my hands at the time) placing in top 3, leads me to believe they might not have been given out.

Here's a breakdown of the rounds in which I believe prizes were not given out:

 All were from The Forest. (two uppers and one member, personal prize received but no crew-wide gifts to participating members)

Void was from The Forest (One upper)

Void was from The Forest (One upper)

twigs was from The Forest (One upper - personal rewards received, no gifts were given to crewmembers who participated in event)

Void was from The Forest (One upper)

Minor correction, Daiquiri was not an upper at the time. I deleted her placements in the breakdown above, but forgot to edit her name out of the text.

I asked my crew what they received for the times I placed I was Valinor's LH at the time.  They told me they didn't win anything, but we didn't mention it because you were having some internet issues at the time.
