I've been working on (another) UI I'm trying to create, and I figured I may as well kill two birds with one stone, so I'm testing it on a char on Test Server. The patches listed above are holding so far.
I'll continue to keep an eye on Test, in case anything else comes up, but it isn't my regular server, so if something changes there, I hope someone from Test will post here that it has, so I can go find out what the changes are.
