Back in v301 a bug was reported about the Pigs in Dyrford displaying an error message when clicked on.

While this has been fixed, when you now click on them a semi transparent square appears over them.

I guess this is a background that is supposed to increase readability of text?

In the case that the pigs do not get some sort of descriptive text back this can be removed as well.

I noticed that, too. The solution here is obviously to name all of them after forum members.

Sorry, I had it wrong in my head. I understood it as them having blank names for some reason, but they don't. They're all named Piglet.

What OP is talking about is this:

Notice the dark box, as if displaying hovertext, yet there is no text.

 

I propose a hearty "Oink", alternated by "Wee, wee", followed finally by "PoE sucks without murderhobo XP".
