Weird floor while expanding, but only certain tiles

This isn't a pressing problem, but I thought I'd highlight it to you anyway.
Please see the two screenshots for comparison.

I was in the the midst of expanding, and I noticed certain floor tiles right at the edge caused a white triangle on the item placed on them, but certain tiles didn't. I've never seen his before, but then again, I didn't always put things at the edge pre-expansion... My screenshots show how the aquarium was affected (or not) depending on where I put it. Oh, if it helps to know, this was my last expansion (I can't expand any further).
