It's broken. Just bought the bomb from vendor, got nothing.
Steam Achievement Star-Spangled Bomber
It's actually good for a lot longer then just today.
I was told you can always get the achievement from here on out, but you only get the ticket during the day it's posted.
Nice.
The achiev don't exist anymore.
Want my money back.
Sorry about the mix up guys, please keep an eye out for this achievement on a later date of the event. Also, so long as you have a Firecracker bomb when it goes live, you will earn the achievement, so no worries!
Ticket'll show up so long as the event is still going on, doesn't have to be today. Don't be in a rush, we have until the 10th guys.
Meanwhile, people are selling firecrackers for a good profit.
Until everyone noticed it's bugged.
"The Spiral Knight achievement for the Summer Camp Sale, 'Star Spangled Bomber' will be available Wednesday, July 6th.
The achievement requires that you have a Firecracker bomb in your arsenal. If you have already acquired this bomb, simply log in on Wednesday and you will receive the achievement.
Again, you must actually have the bomb in your arsenal on Wednesday for you to earn the achievement. If you had one previously and no longer do, you will not get the achievement."

Wednesday, it is.
Also, guys, even if it had been for today, you CAN earn tickets for previous days' achievements and they count both for prize redemption and for the grand prize drawing. I looked that up in an official steam FAQ about the summer event. :)
Now if only there was a Spiral Knights prize to spend those tickets on. ;)
Yeah, I made a post in the Bugs section of the forums about this.
I hope they get on it soon, as the achievement's only good for today. At least as far as getting a ticket.
