I constantly get this error when I try to click on a floating piece of litter. I've looked up possible ways to fix it; I've cleared the cache and cookies and restarted Chrome with only one tab open, but it still always does the same thing.
If you open two tabs and on both appears floating items (and you try to collect both of them), you get this message.

Yes, as stated before it happens when you browse with multiple tabs. There is nothing to fix. Just have to be alert to collect the trash as soon as it pops up.
And... Don't worry of you miss it. Another one is just a few clicks away. ;)
Edited for typos.
Please read my first post. I only use one tab and still receive the error message. I don't mind it, really, I'm just not able to receive anything this way and was wondering if I could get some free instead having to buy them from shops. xD
