I can’t believe you made it this far, you rock!
here is the last missing piece to complete this puzzle…
…but if this is the only piece you’ve found so far, maybe it’s a good idea to focus on the game again, you’ve probably missed something…
put the 4 pieces together and see the sentence formed. Access this link: Finding the lost booster
Comment your UID number and the phrase formed by the four images of puzzle pieces and help the lost booster find its way to you…

hate for anyone to miss out on a technicality… 
Fun little treasure hunt, thank you to whoever got me totally distracted from housework for a bit… 
Hello everyone,
Please comment on the sentence and the UID only on the form.
Please do not forget that your UID is your account number, and it should never be posted publicly, this way we can guarantee that your account will be safe.
Also, remember that it is essential to comment your UID on the form because it is through it that I will be able to send the booster to you, if you do not comment on your UID, I will not be able to know what your account is and therefore I will not be able to send the booster.
For those who have already sent the answer in the form, you will soon receive your booster in your inbox.

New things like this are an appreciated treat
Yes, things like this that are new, different, and get everyone running to social media to talk about it are definitely a nice treat. Keep up the good work!!
I’m guessing that it’s an update caused by this quest that’s caused a number of player’s games to crash to OS just now
Hey,
I saw that some people put the words highlighted in the captions in the form: “Facebook, Instagram, Forum”. These words are hints of where it would be possible to find the next image of the puzzle.
To find the sentence that you must comment on the form, check the four images posted, each of them has a small excerpt of a sentence. For example, in the image posted here, the phrase is: “at your side”
Put together the excerpts of each image to complete the sentence and then comment on the form

Should I get the reward immediately? I put in the sentence and his.
I’m not sure how long it will take, I’ve sent it awhile ago and haven’t gotten anything in my inbox yet either.
Hey Valiant,
I’m sending the rewards manually, so it might take a while to send everyone, but I’m trying to send them as fast as possible, so you should receive your reward soon.
Thanks for your patience.

Nice, this is a bit of fun, who doesn’t love a treasure hunt! I submitted twice because I missed a part of the sentence first time - doh!!
I ended up submitting incorrect responses twice before realizing there was another piece. Finally got it. Sorry you have to manually apply them. Hope you have a great 4th of July.
Awesome reward, thank you Rebeca and team!
Hey guys,
Keep submitting your answers, the deadline is tomorrow at 4:00 PM UTC!
I sent the booster to everyone who submitted responses by 8:20 PM UTC.
If you sent your answer before this time and did not receive your reward, please check again, something may be missing from your reply, like your UID or some detail in the sentence.
If you sent your answer after this time, don’t worry, tomorrow I’ll keep sending the missing rewards 
Thank you to everyone who is participating 
Rebeca.
This was a fun little side track to do while chillin and grillin. Thanks guys!
Sounds like you’re putting in a lot of work on this Rebeca. Thank you!
This was a fun quest! Thank you for the awesome reward! 
OH sorry for the double submission then. I thought it was automatic. I’ll wait patiently.
Looks like he sent…

Sorry, I sent a second time because I mixed up the sentence. Because I’m not very good at English.

I sent this message. But for some reason I didn’t get the bounty when I corrected my mistake i.e. text order from puzzle.
If you didn’t get it, what do you do? Here is an example, if a person tried to find 4 pieces, but did not receive a reward, what to do with it?
Even 5 hours have passed and nothing happens.
Have folks who submitted received the reward? I submitted mine twice (sorry about that!) to make sure I had it right but have not received anything. This was a cool surprise, though!
