Dude, where's my car?

I don't fully play the out of camp events, but I do try to cash in at least the first five or so rewards. I am sure I got these rewards today because I got those "would you like to spend all your gems on the off chance that we don't give you three crappy fruit trees?" "offer". Problem: I didn't move them to the proper loot areas right off. I got distracted by the dragonia trades. Now, I can't find the darn loot bubbles. The little buggers are hidden in my camp somewhere and they're grrrr frustrating. This is not the first time this has happened to me. Any advice? I play on a little phone screen and my eyes are crap.
