Star Wars: The Old Republic was patched yesterday to version 1.0.2, squashing a lengthy list of bugs that notably did not include the glitch that renders dancing characters invulnerable to enemy attacks. A post in the game's Community News web portal promised that the issue would be addressed this week, and now it has been.
Patch 1.0.2b is now live, doing away with the "/getdown glitch" and addressing an issue that causes some players to lose access to the in-game chat channels. That's all though. The bulk of the fixes came yesterday in 1.0.2, which you can check out the patch notes for on the game's official website. There's not much in the way of re-balancing though; mostly just bug-squashing and creating a more functional game for you to play.
