That's the thing. Everything is up-to-date and I run system checks regularly. I reinstalled Flash before posting this thread just in case it happens to be outdated and it wasn't. Chrome is up-to-date as well, so there shouldn't be a reason why this is happening. The "bug" itself is very strange because it only affects one world through one browser (so far). I use a pretty high-end gaming PC, so it's not that I can't load my world anymore, as that would be silly. It isn't top notch, but it was able to keep my city loaded for over two years. Plus, nothing really happened in particular when this first began. I didn't build anything and I didn't receive any updates to any of my software. The closest thing I could suggest to be the cause of this issue is Chrome itself, but why does it load D-G even though it doesn't load A?
