I just now got another one of these invalid items. It had a broken item image too. I think it was while buying something at Spells Galore.
Broken floater image just now playing Item Scramble, not sure if this will help but:

That is the link location when I right click on it.
RIP Mom, I love & miss you more than you know. Tell Dede hi.

THANK YOU! NHS... Think pink this October..
Today i have had many broken image and when i took a floating item the pop up didn't load and the item not been put in my inventory =(
this still happening http://img.subeta.net/items/
I've had two of these (broken image, and an error when I click on it) since Scarsdale said it was fixed :(

I'm seeing a bunch of these this morning. :( Broken image and error when clicking.
I am still getting these today, every so often. It's only frustrating because the floaters pop up so rarely for me already
I just got one. Didn't catch the URL or anything. Broken floater image.
I have had this issue too since Fireside started. I also missed a great many I think because earlier today I noticed most aren't even showing up with a picture but as a very small box with an x in it that doesn't really stand out against the background. I have been very active on Subeta these past few days in the hope of getting plenty of floating items, but not a great many to show for it yet. Would I stand a better chance of receiving "good" floating items if I remove that code to make them show up in the upper left corner or does the problem occur whether or not you have that enabled?
All my floating items were fine until 4 pm subeta time today, now I am only getting the broken images.
Clicked on the image, source given as:
Fingers crossed for a fast fix! :)
The 'top corner' coding hasn't made any difference for me, but not sure if that is site wide.
Broken image, invalid floater: LINK: http://subeta.net/floating.php?act=claim&xgen=MTc2Mzk3fDMxNjU1fHw=
Just happened to me as well, does the id number 176397 help? <img src="http://img.subeta.net/items/" style="-webkit-box-shadow: rgba(0, 0, 0, 0.1) 5px 5px 5px; -moz-box-shadow: rgba(0, 0, 0, 0.1) 5px 5px 5px;">
Just got another invalid floater. When I clicked on it all it said was "Oh No! Invalid Item - !"
The link (which was very similar to Taffysm's above) was http://subeta.net/floating.php?act=claim&xgen=MTc2Mzk3fDU1Mzk0fHw=
Same as above, a broken image and invalid floater from http://subeta.net/floating.php?act=claim&xgen=MTc2Mzk3fDg4NjU5fHw=.
I did get this message when I clicked on it again (since I still had the tab open): Oh No! We have no record of this floating item (176397)!
